This book was released on 2013 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: Novel methodology developments and applications of a variety of spectroscopic and spatially resolved NMR experiments are presented here. NMR has poor sensitivity, especially for rare spins. We have developed novel relaxation optimized double quantum filtered transition selective experiments to improve the sensitivity of rare spin correlation spectroscopy: Low Abundance Single transition correlation SpectroscopY (LASSY) in direct detection mode and 1H Indirect detected Carbon Low Abundance Single transition correlation Spectroscopy (HICLASS) in the indirect detection mode. These approaches typically halve the measurement time to produce a given sensitivity, in comparison to INADEQUATE CR and ADEQUATE respectively. They may be applied to 13C, 29Si, Sn isotopes, 183W, 77Se, etc. Secondly, the time evolution of multiple quantum coherences under spin lock has been studied in spin-1/2 A2X2 systems, and is shown to result in 'amplified' homonuclear scalar couplings. Further, the utility of spatially resolved NMR, ie, MRI and MRS is demonstrated for electrochemical applications such as membrane permeability studies. Finally, flow field imaging of an H2-O2 fuel cell under load is presented

These have, in many cases, already become established techniques in NMR laboratories, in both academic and industrial establishments. A considerable amount of information and guidance is given on the implementation and execution of the techniques described in this book.

Download or read book NMR Imaging of Materials written by Bernhard Blumich and published by OUP Oxford. This book was released on 2000-08-10 with total page 565 pages. Available in PDF, EPUB and Kindle. Book excerpt: NMR imaging of materials is a field of increasing importance. Applications expand from fundamental science like the characterization of fluid transport in porous rock, catalyst pellets, and hemodialyzers into various fields of engineering for process optimization and product and quality control, for example, of polymer materials, biomaterials, elastomers, and ceramics. While the results of NMR imaging are being appreciated in a growing community, the methods of imaging are far more diverse for materials applications than for medical imaging of humans. This book provides an introduction to NMR imaging of materials covering solid-state NMR spectroscopy, imaging methods for liquid and solid samples, and unusual NMR in terms of special approaches to spatial resolution like an NMR surface scanner. Special attention is paid to the large variety of ways to generate image contrast - the most prominent feature of NMR. The text is strong on methodology, and includes today's important application areas.

Download or read book Methods for Structure Elucidation by High Resolution NMR written by G. Batta and published by Elsevier. This book was released on 1997-12-04 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nuclear Magnetic Resonance Spectroscopy (NMR) is now widely regarded as having evolved into a subscience. The field has become immensely diverse, ranging from medical use through solid state NMR to liquid state applications, with countless books and scientific journals devoted to these topics. Theoretical as well as experimental advance continues to be rapid, and has in fact accelerated by many novel innovations. This multi-authored book focuses on the latest developments in the rapidly evolving field of high resolution NMR, specifically with a view to applications on the structure elucidation of organic molecules of moderate molecular weight. Conceptually it differs from basic educational texts, hard-core scientific papers and regular review articles in that each chapter may be regarded as the authors' personal account of their special insights and results that crystallised after several years of research into a given topic. The book revolves around several themes and offers a handful of scientific "gems" of various colors, reflecting the great diversity of NMR. It contains 16 loosely connected chapters written by some of today's most accomplished NMR scientists in the world. Each chapter is a unique synthesis of the authors' previous research results in the given field, and thus projects special insights. Much emphasis has been given to the latest developments in NMR, in particular to selective pulses and pulsed field gradients. As a part of the series "Analytical Spectroscopy Library", with subsequent editions coming along this book should provide a platform for future research accounts of similar flavor. The material is presented in a mostly non-mathematical fashion, and is intended mainly for chemists, application NMR scientists and students with already some background in NMR. Some of the chapters slightly overlap in the discussed topics, which is particularly exciting in terms of gaining insight into the same area from different angles.

Download or read book High Resolution NMR in Solids Selective Averaging written by Ulrich Haeberlen and published by Elsevier. This book was released on 2012-12-02 with total page 205 pages. Available in PDF, EPUB and Kindle. Book excerpt: High Resolution NMR in Solids: Selective Averaging presents the principles and applications of the four approaches to high resolution NMR in solids — magic-angle sample spinning, multiple-pulse, proton-enhanced nuclear induction, and indirect detection methods. Divided into six chapters, this book initially describes the tensorial properties of nuclear spin interactions in both ordinary and spin spaces. It then deals with the manifestations of nuclear magnetic shielding in NMR spectra of both single-crystal and powder samples, and then discusses the techniques for analyzing spectra and rotation patterns in terms of shielding tensors. A wide range of NMR phenomena that are result of intentional or natural, selective or unselective averaging processes and the average Hamiltonian theory that yields the inclusion of correction are covered. This book also provides a detailed discussion on multiple-pulse sequences intended for high resolution NMR in solids. The concluding chapter examines the applications of multiple-pulse techniques, with particular emphasis on measurements of 19F and 1H shielding tensors. Discussions on rotations of angular momentum operators; time ordering and the Magnus expansion; off-resonance averaging of the second-order dipolar Hamiltonian; and phase transients are covered in the supplemental texts.

This book was released on 2012-12-06 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: The magnetism of nuclear spin systems has proved an amazingly fertile ground for the creativity of researchers. This happy circumstance results from the triple benediction that nature appears to have bestowed on nuclear spins: they are sporting spies-being infinitely manipulable (one is even tempted to say malleable), not unduly coy in revealing their secrets, and having a whole treasure house of secrets to reveal in the first place. researcher with Since spin dynamics are now orchestrated by the NMR ever more subtle scores, it is important to be able to tune into the pro ceedings with precision, if one is to make sense of it at all. Fortunately, it is not terribly difficult to do so, since in many ways spin dynamics are the theoretician's dream come true: they are often finite dimensional and quite tractable with basic quantum mechanics, frequently allowing near exact treatments and readily testable predictions. This book was conceived two years ago, with the objective of providing a simple, consistent introduction to the description of the spin dynamics that one encounters in modern NMR experiments. We believed it was a good time to attempt this, since it was possible by then to give sufficiently general descriptions of powelful classes of new NMR experiments. The choice of experiments we discuss in detail is necessarily subjective, al though we hope to have given a flavor of most of the important classes of pulse sequences, including some surface coil imaging applications.

Download or read book NMR Spectroscopy in Drug Development and Analysis written by Ulrike Holzgrabe and published by John Wiley & Sons. This book was released on 2008-07-11 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the development of the NMR spectrometer in the 1950s, NMR spectra have been widely used for the elucidation of the 2D structure of newly synthesized and natural compounds. In the 1980s, the high-resolution NMR spectrometer (> 300 Mhz) and 2D experiments were introduced, which opens up the possibility to determine the 3D structure of large molecules, especially biomolecules. However, NMR spectroscopy has been rarely applied to drug analysis. This book illustrates the power and versatility of NMR spectroscopy in the determination of impurities in and the content of drugs, the composition of polymer excipients, the characterization of isomeric drug mixtures, the complexity of drugs with small-size components or ions, and the behavior of drugs in acid and basic solution. In addition, NMR spectroscopy and especially the hyphenated technique with HPLC is shown to be a powerful tool to measure a drug and its metabolites in various body fluids. The solid state NMR technique can give information on the structure, especially the conformation of drugs and excipients in drug formulations. Recently, SAR by NMR, introduced by Fesik, impressively demonstrated the potential of NMR spectroscopy in drug development and in the characterization of the interaction between large molecules and ligands. The complexation between proteins, lipids and cyclodextrins with drugs is described. Finally, NMR imaging (MRI and MRS) can be used to characterize the liberation of drugs from a drug formulation. Furthermore, the distribution of substances in plants, in animals, in tissues and in humans can be visualized by imaging. In short, this book covers all aspects of drug analysis.

Download or read book Ultra High Resolution NMR Methods and Its Applications written by Upendra Singh and published by . This book was released on 2023-01-15 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ultra-high resolution nuclear magnetic resonance (NMR) methods refer to advanced techniques used to obtain detailed structural information about molecules. These methods use high-field magnets and specialized pulse sequences to achieve very high resolution in the NMR spectrum, allowing for the detection of very small chemical shifts and coupling constants. One of the main applications of ultra-high resolution NMR methods is in the study of biological macromolecules, such as proteins and nucleic acids. These methods can be used to determine the three-dimensional structure of these molecules, which is important for understanding their function and for drug design. Ultra-high resolution NMR methods can also be used for the study of small molecules. These methods can be used to determine the conformation of a molecule in solution, which is important for understanding the properties of a molecule and for designing new materials. In addition, ultra-high resolution NMR can be used for quantitative analysis of complex mixture. The high resolution of the spectrum allows for the detection of very small amounts of impurities or contaminants, and can also be used to determine the concentration of a component in a mixture. Overall, ultra-high resolution NMR methods are powerful tools that can provide detailed structural information about molecules and can be used in a wide range of applications, including biology, chemistry, and materials science. Nuclear magnetic resonance (NMR) spectroscopy is a potent analytical tool to comprehend physical and chemical nature (mobility, dynamics and kinetics) of small to medium size molecules for an extensive range of samples under variety of conditions such as temperature, concentration, and pH. A wealth of information related to molecular properties and interactions can be furnished by using NMR which could consequently provide utility in molecular structural identification. However, low sensitivity along with low resolution is a concern in application of NMR. Within the past few decades, NMR sensitivity has improved significantly through advancement in instrumentation as well as methodological developments. Recent upgrade in NMR instrumentation such as cryogenically cooled probes[1] has led to increase sensitivity and three to four-times better signal /noise ratio in comparison to room temperature probes leading to faster acquisition times and improved sensitivity. Resolution of spectrum is additionally improved in a high magnetic field which disperses the chemical shifts over the broad frequency range (in Hz). Nevertheless, signal overlaps continue being a limiting factor for characterizing complicated spectra. Therefore, a steady development of new pulse sequences and enhancements of the existing ones are of vital importance in improving the overall performance of NMR spectroscopy.

This book was released on 2012-12-06 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: Solid-State NMR is a branch of Nuclear Magnetic Resonance which is presently experiencing a phase of strongly increasing popularity. The most striking evidence is the large number of contributions from Solid-State Resonance at NMR meetings, approaching that ofliquid state resonance. Important progress can be observed in the areas of methodological developments and applications to organic and inorganic matter. One volume devoted to more or less one of each of these areas has been published in the preceding three issues. This volume can be considered an addendum to this series. Selected methods and applications of Solid-State NMR are featured in three chapters. The first one treats the recoupling of dipolar interactions in solids, which are averaged by fast sample rotation. Following an introduction to effective Hamiltonians and Floquet theory, different types of experiment such as rotary resonance, dipolar chemical shift correlation spectroscopy, rotational resonance and multipulse recoupling are treated in the powerful Floquet formalism. In the second chapter, the different approaches to line narrowing of quadrupolar nuclei are reviewed in a. consistent formulation of double resonance (DaR) and dynamic angle spinning (DAS). Practical aspects of probe design are considered as well as advanced 2D experiments, sensitivity enhancement techniques, and spinning sideband manipulations. The use of such techniques dramatically increases the number of nuclei which can be probed in high resolution NMR spectroscopy. The final chapter describes new experimental approaches and results of structural studies of noncrystalline solids.
