Book Description

It is amazing how much information can be gleaned from a magnetic resonance spectrum by one who knows. That series of lines on chart paper may conceal anything from energies of activation and spin densities, to conformations and differentiation of isomers. In order to be able to deduce such things about the structure and properties of molecules in a sample, it is necessary to be familiar with the underlying principles, and to arrive at that state of understanding is not easy. This book was conceived and written in an attempt to clarify what is necessary theoretical equipment for anyone wishing to extract the maximum information from a magnetic resonance spectrum. It is also written for those who will find a fascination and great satisfaction in the way this subject, which involves so many sides of modern physics, holds together. It seems to the author, from experience, that the difficulty of getting to grips with the theory of magnetism and magnetic resonance is two sided. On the one hand one has forgotten, or never really known, the principles of electromagnetism on which it is based, and on the other, detailed analysis of the spectra requires a certain facility with the operator techniques of quantum mechanics. In both cases the principle difficulty appears to be unfamiliarity, so the chief aim in this book will be to introduce the enquirer to the relevent language in a reasonably connected fashion.

Book Description

Biological magnetic resonance (NMR and EPR) is a rapidly expanding area of research with much activity in most universities and research institutions. International conferences are held biennially with an increasing number of participants. With the introduction of sophisticated and continuously im proving instrumentation, biological magnetic resonance is approaching the state of a common physical method in biochemical, biomedical, and bio logical research. The lack of monograpbs on the subject had been con spicuous for a long time. This gap started to close only recently. However, because of the rapid expansion and intensive research, many texts are dated by the time of their appearance. Therefore we have undertaken the editing of a series that is intended to provide the practicing chemist, biochemist, or biologist with the advances and progress in selected contemporary topics. In seeking to make the series as authoritative as possible, we have invited authors who have not only made significant contributions but who are also currently active in their fields. We hope that their expertise as well as their first hand experience as reflected in the chapters of this volume will be of benefit to the reader, inter alia, in planning his own experiments and in critically evaluating the current literature.

Book Description

In writing this book I had two main objectives: (1) to teach the organic chemist how to interpret proton magnetic resonance spectra, and (2) to provide the reference data which are constantly needed in the use of proton spectra. I have felt that it was im portant to point out not only the information which can be gained from spectra, but also the limitations and the potential pitfalls. All of the important facts are organized into tabular summaries. Every effort has been made to present the material clearly, con cisely, completely, and accurately. At the same time, subjects not directly related to the interpretation of spectra have been omitted. Thus, while the conclusions drawn from theory are presented, the theory itself has been avoided. There are a number of advantages in learning the empirical facts before learning the theory. First of all, in interpreting spectra one usually has to rely on his knowledge of the accumulated empirical correlations much more than on his knowledge of the theory. In fact, one could know all of the theory and still not b~ able to interpret spectra unless he also knew the empirical facts. Secondly, the theory is much more easilyunderstoodafter the facts have been mastered.

Book Description

This text is aimed at people who have some familiarity with high-resolution NMR and who wish to deepen their understanding of how NMR experiments actually ‘work’. This revised and updated edition takes the same approach as the highly-acclaimed first edition. The text concentrates on the description of commonly-used experiments and explains in detail the theory behind how such experiments work. The quantum mechanical tools needed to analyse pulse sequences are introduced set by step, but the approach is relatively informal with the emphasis on obtaining a good understanding of how the experiments actually work. The use of two-colour printing and a new larger format improves the readability of the text. In addition, a number of new topics have been introduced: How product operators can be extended to describe experiments in AX2 and AX3 spin systems, thus making it possible to discuss the important APT, INEPT and DEPT experiments often used in carbon-13 NMR. Spin system analysis i.e. how shifts and couplings can be extracted from strongly-coupled (second-order) spectra. How the presence of chemically equivalent spins leads to spectral features which are somewhat unusual and possibly misleading, even at high magnetic fields. A discussion of chemical exchange effects has been introduced in order to help with the explanation of transverse relaxation. The double-quantum spectroscopy of a three-spin system is now considered in more detail. Reviews of the First Edition “For anyone wishing to know what really goes on in their NMR experiments, I would highly recommend this book” – Chemistry World “...I warmly recommend for budding NMR spectroscopists, or others who wish to deepen their understanding of elementary NMR theory or theoretical tools” – Magnetic Resonance in Chemistry
