Available in PDF, EPUB and Kindle. Book excerpt: The content of this volume has been added to eMagRes (formerly Encyclopedia of Magnetic Resonance) - the ultimate online resource for NMR and MRI. The term "NMR Crystallography" has only recently come into common usage, and even now causes raised eyebrows within some parts of the diffraction community. The power of solid-state NMR to give crystallographic information has considerably increased since the CPMAS suite of techniques was introduced in 1976. In the first years of the 21st century, the ability of NMR to provide information to support and facilitate the analysis of single-crystal and powder diffraction patterns has become widely accepted. Indeed, NMR can now be used to refine diffraction results and, in favorable cases, to solve crystal structures with minimal (or even no) diffraction data. The increasing ability to relate chemical shifts (including the tensor components) to the crystallographic location of relevant atoms in the unit cell via computational methods has added significantly to the practice of NMR crystallography. Diffraction experts will increasingly welcome NMR as an allied technique in their structural analyses. Indeed, it may be that in the future crystal structures will be determined by simultaneously fitting diffraction patterns and NMR spectra. This Handbook is organised into six sections. The first contains an overview and some articles on fundamental NMR topics, followed by a section concentrating on chemical shifts, and one on coupling interactions. The fourth section contains articles describing how NMR results relate to fundamental crystallography concepts and to diffraction methods. The fifth section concerns specific aspects of structure, such as hydrogen bonding. Finally, four articles in the sixth section give applications of NMR crystallography to structural biology, organic & pharmaceutical chemistry, inorganic & materials chemistry, and geochemistry.

Download or read book NMR Spectroscopy for Probing Functional Dynamics at Biological Interfaces written by Anirban Bhunia and published by Royal Society of Chemistry. This book was released on 2022-08-17 with total page 733 pages. Available in PDF, EPUB and Kindle. Book excerpt: NMR spectroscopy has found a wide range of applications in life sciences over recent decades. Providing a comprehensive amalgamation of the scattered knowledge of how to apply high-resolution NMR techniques to biomolecular systems, this book will break down the conventional stereotypes in the use of NMR for structural studies. The major focus is on novel approaches in NMR which deal with the functional interface of either protein-protein interactions or protein-lipid interactions. Bridging the gaps between structural and functional studies, the Editors believe a thorough compilation of these studies will open an entirely new dimension of understanding of crucial functional motifs. This in turn will be helpful for future applications into drug design or better understanding of systems. The book will appeal to NMR practitioners in industry and academia who are looking for a comprehensive understanding of the possibilities of applying high-resolution NMR spectroscopic techniques in probing biomolecular interactions.

Download or read book Modern Methods in Solid state NMR written by Paul Hodgkinson and published by Royal Society of Chemistry. This book was released on 2018-04-05 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: Solid-state NMR covers an enormous range of material types and experimental techniques. Although the basic instrumentation and techniques of solids NMR are readily accessible, there can be significant barriers, even for existing experts, to exploring the bewildering array of more sophisticated techniques. In this unique volume, a range of experts in different areas of modern solid-state NMR explain about their area of expertise, emphasising the “practical aspects” of implementing different techniques, and illustrating what questions can and cannot be addressed. Later chapters address complex materials, showing how different NMR techniques discussed in earlier chapters can be brought together to characterise important materials types. The volume as a whole focusses on topics relevant to the developing field of “NMR crystallography” – the use of solids NMR as a complement to diffraction crystallography. This book is an ideal complement to existing introductory texts and reviews on solid-state NMR. New researchers wanting to understand new areas of solid-state NMR will find each chapter to be the equivalent to spending time in the laboratory of an internationally leading expert, learning the hints and tips that make the difference between knowing about a technique and being ready to put it into action. With no equivalent on the market, it will be of interest to every solid-state NMR researcher (academic and postgraduate) working in the chemical sciences.

Download or read book Nuclear Magnetic Resonance written by Krystyna Kamienska-Trela and published by Royal Society of Chemistry. This book was released on 2012 with total page 499 pages. Available in PDF, EPUB and Kindle. Book excerpt: As a spectroscopic method, nuclear magnetic resonance (NMR) has seen spectacular growth, both as a technique and in its applications. Today's applications of NMR span a wide range of scientific disciplines, from physics to biology to medicine. Each volume of Nuclear Magnetic Resonance comprises a combination of annual and biennial reports which together provide comprehensive coverage of the literature on this topic. This Specialist Periodical Report reflects the growing volume of published work involving NMR techniques and applications, in particular NMR of natural macromolecules, which is covered in two reports: NMR of Proteins and Nucleic Acids and NMR of Carbohydrates, Lipids and Membranes. In his foreword to the first volume, the then editor, Professor Robin Harris announced that the series would be a discussion on the phenomena of NMR and that articles will be critical surveys of the literature. This has certainly remained the case throughout the series, and in line with its predecessors, Volume 40 aims to provide a comprehensive coverage of the relevant NMR literature. For the current volume this relates to publications appearing between June 2009 and May 2010 (the nominal period of coverage in volume 1 was July 1970 to June 1971). Compared to the previous volume there are some new members of the reporting team. Theoretical Aspects of Spin-Spin Couplings are covered by J. Jazwinski, while E. Swiezewska and J.W̤jcik provide an account of NMR of Carbohydrates, Lipids and Membranes.

This book was released on 2012-12-06 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nuclear magnetic resonance spectroscopy, which has evolved only within the last 20 years, has become one of the very important tools in chemistry and physics. The literature on its theory and application has grown immensely and a comprehensive and adequate treatment of all branches by one author, or even by several, becomes increasingly difficult. This series is planned to present articles written by experts working in various fields of nuclear magnetic resonance spectroscopy, and will contain review articles as well as progress reports and original work. Its main aim, however, is to fill a gap, existing in literature, by publishing articles written by specialists, which take the reader from the introductory stage to the latest development in the field. The editors are grateful to the authors for the time and effort spent in writing the articles, and for their invaluable cooperation. The Editors Contents c. W. Hilbers and C. MacLean NMR of Molecules Oriented in Electric Fields.

Download or read book High resolution Solid state NMR for Powder Crystallography written by Elodie Salager and published by . This book was released on 2010 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: Knowledge of the three-dimensional structure is an invaluable element for the understanding of the properties of solid materials and towards the development of new materials. While single-crystal X-ray diffraction is established as the best tool to characterise monocrystalline samples, the experimental determination of the structure of polycrystalline powders remains a challenging domain. Many crystalline solids cannot be prepared as single crystals and must be characterized in the powder form. Other compounds are highly subject to polymorphism, and there is a need for structural determination techniques that minimize the risk of structural change during the characterisation. The problem is particularly relevant in the case of drug powders, which need to be accurately characterized in their active pharmaceutical form. This thesis presents new developments relating to powder nuclear magnetic resonance (NMR) crystallography, i.e. structure determination of powdered samples using high-resolution solid-state NMR at natural isotopic abundance. The first part of the thesis concentrates on the challenging case of protons and illustrates the opportunities offered by the latest generation of commercial NMR probes and new decoupling methods. Protocols are proposed in the second part, which benefit of the high-resolution solid-state NMR spectra accessible for protons and carbons and which make use of the strong dependence of the NMR parameters on crystalline structure details. These techniques are successfully applied to a model compound, thymol, and demonstrate the potential of solid-state NMR for structural determination of powdered compounds.

Download or read book The Scientific Truth the Whole Truth and Nothing but the Truth written by John R. Helliwell and published by CRC Press. This book was released on 2024-04-05 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a limited understanding amongst scientists, students, and the public about realizing trust in scientific findings. This should be a paramount objective. Scientists and the public need to know more about the link between the philosophy of science and science research methods. There is a limited understanding of why accuracy is important and that it is not the same as precision. Also, there is often the need to be pragmatic and so measure an approximation of a real system, and the classic case is reductionism in biology versus whole organism biology. The author brings these topics together in terms of trusting in science. Features Covers how scientific truth is perceived and increases the preparedness of early career scientists. Examines the relatively new field of machine learning and artificial intelligence as applied to crystallography databases in biology and chemistry for new discoveries. Describes the major changes in digital data archiving and how vast “raw data” archives are being increasingly developed for machine learning and artificial intelligence as well as complete truth. This unique volume will be of interest to pre-university and university undergraduate students, principally in science. Presents scientific research examples from physics, chemistry, and biology together with their methodologies.
