Book excerpt: The field of Nuclear Magnetic Resonance (NMR) has developed at a fascinating pace during the last decade. It always has been an extremely valuable tool to the organic chemist by supplying molecular "finger print" spectra at the atomic level. Unfortunately the high resolution achievable in liquid solutions could not be obtained in solids and physicists and physical chemists had to live with unresolved lines open to a wealth of curve fitting procedures and a vast amount of speculations. High resolution NMR in solids seemed to be a paradoxon. Broad structure less lines are usually encountered when dealing with NMR in solids. Only with the recent advent of mUltiple pulse, magic angle, cross-polarization, two-dimen sional and multiple-quantum spectroscopy and other techniques during the last decade it became possible to resolve finer details of nuclear spin interactions in solids. I have felt that graduate students, researchers and others beginning to get involved with these techniques needed a book which treats the principles, theo retical foundations and applications of these rather sophisticated experimental techniques. Therefore I wrote a monograph on the subject in 1976. Very soon new ideas led to the developement of "two-dimensional spectroscopy" and "multiple-quantum spectroscopy", topics which were not covered in the first edition of my book. Moreover an exponential growth of literature appeared in this area of research leaving the beginner in an awkward situation of tracing back from a current article to the roots of the experiment.

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.

Available in PDF, EPUB and Kindle. Book excerpt: This volume is an ideal starting point for the graduate student seeking a basic introduction to the theory and uses of solid-state nuclear magnetic resonance (NMR) spectroscopy. Accessible to students with only a survey-level physics background, the material assumes little prior knowledge of the basic theory of electromagnetism. All the major areas are covered, including an introduction to concepts of time-dependent quantum mechanics as they apply to NMR spectroscopy of the solid state. Each chapter includes problems designed to enhance the reader's understanding of the material. Instructive and practical, this volume provides the basic knowledge needed to access the general literature and the more advanced monographs on this subject. In addition to assisting entrance into the field, Transient Techniques in NMR of Solids will be a useful guide for professionals already working in related areas of chemistry. FROM THE PREFACE: Nuclear magnetic resonance (NMR) is truly a remarkable phenomenon. Remarkable can imply different things to different people. From the point of view of a physicist, spin dynamics is an elegant example of the use of time-dependent quantum mechanics, and NMR absorption of energy is a prototype for spectroscopic transitions. From the point of view of the practicing chemist and materials scientist, NMR spectroscopy is an invaluable tool for the identification of chemical species and structures. Had NMR spectroscopic techniques commercially available in the early 1960s been the only result of investigations of this phenomenon, it would have had a major impact on the course of chemical analysis. The study of liquids and solutions for chemical shifts and couplings of protons had produced a rapid means of identifying chemical species nondestructively. The study of dynamical properties also could be addressed by study of temperature dependence of the spectra or of the saturation of the resonance by high-power irradiation. Even at that time, however, studies of the spin dynamics had already begun to indicate that there were many interesting facets of the NMR phenomenon left to exploit. For example, the Fourier-transform relationship of the free-induction decay and the absorption spectrum had been shown and the basis of the cross-polarization experiment was being investigated. A number of chemists had begun to study the spin*b1lattice relaxation times of species by pulse NMR techniques by utilizing methods that were not familiar at that time to the typical chemist but that are now commonly employed in NMR analysis. The principal characteristic of the NMR technique that makes it so useful for chemical analysis of liquids and solutions is the high resolution that allows one to observe very small interactions such as the chemical shift and the spin*b1spin coupling. These weak interactions are quite sensitive to the local environment of the spin and therefore may be used as a diagnostic for the environment. The connectivity of chemical structure is often mimicked closely in the NMR connectivity of the spectrum, and quantitative informaton is relatively easy to obtain. Nuclear magnetic resonance spectra of solids exhibit such resolution only in special cases. The primary (although not the exclusive) reason for the lack of resolution in the spectrum of a typical solid is the presence of the dipole*b1dipole interaction, which dominates the NMR spectroscopy of solids that have been of interest to chemists. One solution (no pun intended) to the problem of obtaining chemical-shift information about such solids is to dissolve them and to study them in solution. However, if the solid is insoluble or otherwise intractable or if the analysis involves questions about the properties of the substance in the solid state, then there arises a need for techniques to study the weaker interactions in the presence of the dipole*b1dipole interaction or other overwhelming interactions. This volume describes the means dev

This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Solid state NMR has the ability to obtain detailed structural information at the molecular level in materials. This has led to the development of a large number of high resolution techniques, some of which utilize multiple pulse methods. The behaviour of these multiple pulse techniques has, to date, been explained using either relaxation or spin dynamics. Ultimately, an explanation based on a combination of both dynamics is required in order to properly understand the underlying mechanism of these techniques. This work presents an explanation of the experimental behaviour observed for three multiple pulse domain selection techniques: the DIVAM, Direct DIVAM, and Refocused DIVAM sequences. This is based on a combination of spin and relaxation dynamics and is accomplished using both analytical expressions and simulations obtained using a general simulation program for solid-state NMR spectroscopy (SIMPSON).

Available in PDF, EPUB and Kindle. Book excerpt: Advances in Magnetic Resonance: The Waugh Symposium, Volume 14 is a collection of manuscripts presented at the 1989 symposium on “High Resolution NMR in Solids , held at the Massachusetts Institute of Technology. The contributors provide 20- to 30-page articles consistent with AMR’s traditional emphasis on quantitative analysis of NMR techniques. Organized into 13 chapters, this book discusses the principles triple-quantum filtered two-dimensional exchange spectroscopy and its application in the measurement of cross correlation between pairs of dipole-dipole interactions. It then describes alternative ways of using fictitious spin in pulsed nuclear quadrupole resonance or NMR. General topics on the application of optical spectroscopy; the saturation of spin-spin energy by slow continuous bulk rotation; the frequency-switched Lee-Goldburg pulse cycle; and high-resolution proton NMR in solid systems are also explored. A chapter examines an entirely different view of spin dynamics in the presence of radio-frequency fields. This book also deals with the theoretical background and application of solid-state and zero-field NMR spectroscopies to structure determination. Lastly, the utilization of the Floquet formalism in the design of broadband propagators in two-level systems and the two classes of novel NMR phenomena related to the symmetrization postulate are discussed. Analytical and quantum chemists, physicists, biochemists, and materials science researchers will find this book invaluable.

Book excerpt: Solid State NMR A thorough and comprehensive textbook covering the theoretical background, experimental approaches, and major applications of solid-state NMR spectroscopy Nuclear Magnetic Resonance (NMR) spectroscopy is a powerful non-destructive technique capable of providing information about the molecular structure and dynamics of molecules. Alongside solution-state NMR, a well-established technique to study chemical structures and investigate physico-chemical properties of molecules in solutions, solid-state NMR (SSNMR) offers many exciting possibilities for the analysis of solid and soft materials across scientific fields. SSNMR shows unique capabilities for a detailed investigation of structural and dynamic properties of materials over wide space and time ranges. For this reason, and thanks to significant advances in the past several years, the application of SSNMR to materials is rapidly increasing in disciplines such as chemistry, physics, and materials and life sciences. Solid State NMR: Principles, Methods, and Applications offers a systematic introduction to the theory, methodological concepts, and major experimental methods of SSMR spectroscopy. Exploring the unique potential of SSNMR for the structural and dynamic characterization of soft and either amorphous or crystalline solid materials, this comprehensive textbook provides foundational knowledge and recent developments of SSNMR, covering physical and theoretical background, experimental methods, and applications to pharmaceuticals, polymers, inorganic and hybrid materials, liquid crystals, and model membranes. Written by two expert authors to ensure a clear and consistent presentation of the subject, this textbook: Includes a brief introduction to the historical aspects and broad theoretical background of solid-state NMR spectroscopy Provides helpful illustrations to explain the various SSNMR concepts and methods Features accessible descriptive text with self-consistent use of quantum mechanics Covers the experimental aspects of SSNMR spectroscopy and in particular a description of many useful pulse sequences Contains references to relevant literature Solid State NMR: Principles, Methods, and Applications is the ideal textbook for university courses on SSNMR, advanced spectroscopies, and a valuable single-volume reference for spectroscopists, chemists, and researchers in the field of materials.

Available in PDF, EPUB and Kindle. Book excerpt: With the power and range of modern pulse spectrometers the compass of NMR spec troscopy is now very large for a single book-but we have undertaken this. Our book covers the Periodic Table as multinuclear spectrometers do, and introductory chapters are devoted to the essentials of the NMR experiment and its products. Primary products are chemical shifts (including anisotropies), spin-spin coupling constants, and relaxation times; the ultimate product is a knowledge of content and constitution, dynamic as well as static. Our province is chemical and biochemical rather than physical or technical; only passing reference is made to metallic solids or unstable species, or to practical NMR spectroscopy. Our aim is depth as well as breadth, to explain the fundamental processes, whether of nuclear magnetic shielding, spin-spin coupling, relaxation, or the multiple pulse sequences that have allowed the development of high-resolution studies of solids, multidimensional NMR spectroscopy, techniques for sensitivity enhancement, and so on. This book therefore combines the functions of advanced textbook and reference book. For reasonably comprehensive coverage in a single volume we have sum marized the information in tables and charts, and included all leading references.
