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

Download or read book Solid State NMR Spectroscopy for Biopolymers written by Hazime Saitô and published by Springer Science & Business Media. This book was released on 2006-08-05 with total page 455 pages. Available in PDF, EPUB and Kindle. Book excerpt: ‘‘Biopolymers’’ are polymeric materials of biological origin, including globular, membrane, and fibrous proteins, polypeptides, nucleic acids, po- saccharides, lipids, etc. and their assembly, although preference to respe- ive subjects may be different among readers who are more interested in their biological significance or industrial and/or medical applications. Nevert- less, characterizing or revealing their secondary structure and dynamics may be an equally very important and useful issue for both kinds of readers. Special interest in revealing the 3D structure of globular proteins, nucleic acids, and peptides was aroused in relation to the currently active Structural Biology. X-ray crystallography and multidimensional solution NMR sp- troscopy have proved to be the standard and indispensable means for this purpose. There remain, however, several limitations to this end, if one intends to expand its scope further. This is because these approaches are not always straightforward to characterize fibrous or membrane proteins owing to extreme difficulty in crystallization in the former, and insufficient spectral resolution due to sparing solubility or increased effective molecular mass in the presence of surrounding lipid bilayers in the latter.

This book was released on 1996-03-21 with total page 680 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first edition of this book was written in 1961 when I was Morris Loeb Lecturer in Physics at Harvard. In the preface I wrote: "The problem faced by a beginner today is enormous. If he attempts to read a current article, he often finds that the first paragraph refers to an earlier paper on which the whole article is based, and with which the author naturally assumes familiarity. That reference in turn is based on another, so the hapless student finds himself in a seemingly endless retreat. I have felt that graduate students or others beginning research in magnetic resonance needed a book which really went into the details of calculations, yet was aimed at the beginner rather than the expert. " The original goal was to treat only those topics that are essential to an understanding of the literature. Thus the goal was to be selective rather than comprehensive. With the passage of time, important new concepts were becoming so all-pervasive that I felt the need to add them. That led to the second edition, which Dr. Lotsch, Physics Editor of Springer-Verlag, encouraged me to write and which helped launch the Springer Series in Solid-State Sciences. Now, ten years later, that book (and its 1980 revised printing) is no longer available. Meanwhile, workers in magnetic resonance have continued to develop startling new insights.

Available in PDF, EPUB and Kindle. Book excerpt: The last decade or so has seen a dramatic increase in the amount of detailed structural information available from a range of experimental techniques. Exciting new techniques such as atomic force microscopy have become widely available, while the potential of established methods like X-ray diffraction and electron microscopy has been greatly enhanced by powerful new sources and analytical methods. Progress in computing has also had a widespread impact: in areas such as neutron scattering, large data sets can now be manipulated more readily. The software supplied with commercial instruments generally provides more sophisti cated analytical facilities, while time-resolved X-ray studies rely on rapid data handling capabilities. The polymer scientist is faced with an expanding array of experimental tools for addressing both fundamental science and industrial problems. This work reviews some recent developments in structural techniques, with the aim of presenting the current 'state of the art' in a selection of areas.

This book was released on 2013-04-17 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: Why to apply solid-state NMR? - By now, we should have learned that NMR is mainly used for the study of molecules in solution, while x-ray diffraction is the method of choice for solids. Based on this fact, the two recent 'NMR-Nobelprizes' went indeed into the liquid phase: my own one eleven years ago, and particularly the most recent one to Kurt Wuthrich. His prize is beyond any doubts very well justified. His contribution towards the study of biomolecules in solution, in their native (or almost native) environment is truly monumental. We all will profit from it indirectly when one of our future diseases will be cured with better drugs, based on the insightful knowledge gained through liquid-state NMR. Two fields of NMR are still left out of the Nobel Prize game: magnetic reso nance imaging (MRI) and solid-state NMR. The disrespect for MRI in Stockholm is particularly difficult to understand; but this is not a subject to be discussed at the present place. Solid-state NMR is the third of the three great fields of NMR, powerful already today and very promising for the near future.

Download or read book Hydrogen Storage Materials written by Darren P. Broom and published by Springer Science & Business Media. This book was released on 2011-02-28 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: The problem of storing hydrogen safely and effectively is one of the major technological barriers currently preventing the widespread adoption of hydrogen as an energy carrier and the subsequent transition to a so-called hydrogen economy. Practical issues with the storage of hydrogen in both gas and liquid form appear to make reversible solid state hydrogen storage the most promising potential solution. Hydrogen Storage Materials addresses the characterisation of the hydrogen storage properties of the materials that are currently being considered for this purpose. The background to the topic is introduced, along with the various types of materials that are currently under investigation, including nanostructured interstitial and complex hydrides, and porous materials, such as metal-organic frameworks and microporous organic polymers. The main features of Hydrogen Storage Materials include: an overview of the different types of hydrogen storage materials and the properties that are of interest for their practical use; descriptions of the gas sorption measurement methods used to determine these properties, and the complementary techniques that can be used to help corroborate hydrogen uptake data; and extensive coverage of the practical considerations for accurate hydrogen sorption measurement that drive both instrument design and the development of experimental methodology. Hydrogen Storage Materials provides an up-to-date overview of the topic for experienced researchers, while including enough introductory material to serve as a useful, practical introduction for newcomers to the field.
