As a spectroscopic method, nuclear magnetic resonance (NMR) has seen spectacular growth over the past two decades, both as a technique and in its applications. Today the 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". For those wanting to become rapidly acquainted with specific areas of NMR, this title provides unrivalled scope of coverage. Seasoned practitioners of NMR will find this an invaluable source of current methods and applications. Volume 37 covers literature published from June 2006 to May 2007.

Keeping mathematics to a minimum, this book introduces nuclear properties, nuclear screening, chemical shift, spin-spin coupling, and relaxation. It is one of the few books that provides the student with the physical background to NMR spectroscopy from the point of view of the whole of the periodic table rather than concentrating on the narrow applications of 1H and 13C NMR spectroscopy. Aids to structure determination, such as decoupling, the nuclear Overhauser effect, INEPT, DEPT, and special editing, and two dimensional NMR spectroscopy are discussed in detail with examples, including the complete assignment of the 1H and 13C NMR spectra of D-amygdain. The authors examine the requirements of a modern spectrometer and the effects of pulses and discuss the effects of dynamic processes as a function of temperature or pressure on NMR spectra. The book concludes with chapters on some of the applications of NMR spectroscopy to medical and non-medical imaging techniques and solid state chemistry of both I = F1/2 and I > F1/2 nuclei. Examples and problems, mainly from the recent inorganic/organometallic chemistry literature support the text throughout. Brief answers to all the problems are provided in the text with full answers at the end of the book.

NMR Spectroscopy in Liquids and Solids provides an introduction of the general concepts behind Nuclear Magnetic Resonance (NMR) and its applications, including how to perform adequate NMR experiments and interpret data collected in liquids and solids to characterize molecule systems in terms of their structure and dynamics. The book is composed of ten chapters. The first three chapters consider the theoretical basis of NMR spectroscopy, the theory of NMR relaxation, and the practice of relaxation measurements. The middle chapters discuss the general aspects of molecular dynamics and their relationships to NMR, NMR spectroscopy and relaxation studies in solutions, and special issues related to NMR in solutions. The remaining chapters introduce general principles and strategies involved in solid-state NMR studies, provide examples of applications of relaxation for the determination of molecular dynamics in diamagnetic solids, and discuss special issues related to solid state NMR— including NMR relaxation in paramagnetic solids. All chapters are accompanied by references and recommended literature for further reading. Many practical examples of multinuclear NMR and relaxation experiments and their interpretations are also presented. The book is ideal for scientists new to NMR, students, and investigators working in the areas of chemistry, biochemistry, biology, pharmaceutical sciences, or materials science.

Dynamic Nuclear Magnetic Resonance Spectroscopy provides an overview of the state of knowledge in dynamic nuclear magnetic resonance (DNMR) spectroscopy. The early chapters describe the theoretical basis and practical techniques which have or will be used for extracting kinetic data from DNMR spectra. The subsequent chapters provide reviews of the many areas in which DNMR spectroscopy has been applied. Key topics covered include nuclear exchange processes; band-shape analysis; application of nonselective pulsed NMR experiments: diffusion and chemical exchange; spin-spin relaxation time determination; rotation about single and double bonds in organic molecules; and dynamic molecular processes in inorganic and organometallic compounds. Also discussed are studies on stereochemical nonrigidity in organometallic and metal carbonyl compounds; fluxional allyl complexes; carbonium ion rearrangements; and proton transfer processes. It is hoped that this volume will provide a literature guide, source book, and progress report which will be helpful to all those who will continue or will begin work in this field.

A blend of theory and practical advice, Modern NMR Techniques for Synthetic Chemistry illustrates how NMR spectroscopy can be used to determine the abundance, size, shape, and function of organic molecules. It provides you with a description the NMR technique used (more pictorial than mathematical), indicating the most common pulse sequences, some practical information as appropriate, followed by illustrative examples. This format is followed for each chapter so you can skip the more theoretical details if the practical aspects are what interest you. Following a discussion of basic parameters, the book describes the utility of NMR in detecting and quantifying dynamic processes, with particular emphasis on the usefulness of saturation-transfer (STD) techniques. It details pulsed–field gradient approaches to diffusion measurement, diffusion models, and approaches to ‘inorganic’ nuclei detection, important as many synthetic pathways to new organics involve heavier elements. The text concludes with coverage of applications of NMR to the analysis of complex mixtures, natural products, carbohydrates, and nucleic acids—all areas of activity for researchers working at the chemistry-life sciences interface. The book’s unique format provides some theoretical insight into the NMR technique used, indicating the most common pulse sequences. The book draws upon several NMR methods that are resurging or currently hot in the field and indicates the specific pulse sequence used by various spectrometer manufacturers for each technique. It examines the analysis of complex mixtures, a feature not found in most books on this topic.
