Nuclear Magnetic Resonance Probes of Molecular Dynamics describes the theoretical basis and experimental techniques that make modern NMR spectroscopy a powerful and flexible tool for probing molecular dynamics in chemical, physical, and biochemical systems. Individual chapters, written by leaders in the development and application of NMR from around the world, treat systems that range from synthetic polymers, liquid crystals, and catalysts to proteins and oligonucleotides and techniques that include deuterium NMR, magic angle spinning, multidimensional spectroscopy, and magnetic resonance imaging. A combination of elementary and advanced material makes the book a useful introduction to the field for students at the graduate level as well as an important reference for practising NMR spectroscopists.

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 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 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 in valuable source of current methods and applications. Specialist Periodical Reports provide systematic and detailed review coverage in major areas of chemical research. Compiled by teams of leading authorities in the relevant subject areas, the series creates a unique service for the active research chemist, with regular, in-depth accounts of progress in particular fields of chemistry. Subject coverage within different volumes of a given title is similar and publication is on an annual or biennial basis.

Intended for researchers and students in physics, chemistry and materials science, this book provides the necessary background information and sufficient mathematical and physical detail to study the current research literature. The book begins with a survey of liquid crystal phases and field effects, together with an introduction to the basic physics of nuclear magnetic resonance. It then discusses orientational ordering and molecular field theories for various liquid crystal molecules and nmr studies of uniaxial and biaxial phases. Subsequent chapters consider spin relaxation processes and rotational, translational, and internal molecular dynamics of liquid crystals. The final chapter discusses two-dimensional and multiple- quantum nmr spectroscopies and their application in elucidating liquid crystal properties. This second edition, updated throughout, incorporates many new references and includes new mathematical appendices.

The Encyclopedia of Spectroscopy and Spectrometry provides authoritative and comprehensive coverage of the whole topic of spectroscopy, from theory to applications. Short articles, each covering one aspect of spectroscopy, provide the professional spectroscopist working in academia or industry with the essential facts and background on areas of spectroscopy peripheral to their own. A list of further reading at the end of each article directs the reader to the level of detail required for professional purposes. Articles are arranged alphabetically, each having been named to facilitate logical access by the reader. Each article is flagged as to which area of spectroscopy it covers ("Mass Spectroscopy," "Magnetic Resonance," etc.) and whether it covers theory, methods and instrumentation, or applications. Users can refer to an alphabetical article listing, or to a listing arranged according to subject area to locate articles. Further reading lists at the end of each article allow easy access to the primary literature. Extensive cross-referencing, a complete subject index, numerous figures, and color plates are included in each volume. Initial access to the online version offering extensive hypertext linking and advanced search tools is available to buyers of the print edition. Ongoing access is maintained for a minimum annual fee.

This book is based on a NATO Advanced Study Institute held to enhance our understanding, at both an experimental and a theoretical level, of the molecular dynamics in liquid crystals. The lecturers at the Institute, each leaders in their respective fields, have contributed chapters to the book with the aim of producing, for the first time, a coherent, pedagogical account of this interdisciplinary subject. The range of materials considered is wide, including lyotropic and thermotropic liquid crystals, biological membranes and polymeric systems. The formalism needed to characterise the rotational, translational and conformational dynamics is developed. Then the use of experimental techniques to investigate the dynamics is described; these techniques include NMR and ESR spectroscopy, neutron scattering, dielectric relaxation, infrared spectroscopy and fluorescence depolarisation. Some of these experiments are influenced by the collective orientations or director modes which are also considered. The results of these experiments are presented and the theory necessary to understand them is described, with particular attention being paid to the influence of the long range liquid--crystalline order on the dynamics.

A quantitative description of the action of enzymes and other biological systems is both a challenge and a fundamental requirement for further progress in our und- standing of biochemical processes. This can help in practical design of new drugs and in the development of artificial enzymes as well as in fundamental understanding of the factors that control the activity of biological systems. Structural and biochemical st- ies have yielded major insights about the action of biological molecules and the mechanism of enzymatic reactions. However it is not entirely clear how to use this - portant information in a consistent and quantitative analysis of the factors that are - sponsible for rate acceleration in enzyme active sites. The problem is associated with the fact that reaction rates are determined by energetics (i. e. activation energies) and the available experimental methods by themselves cannot provide a correlation - tween structure and energy. Even mutations of specific active site residues, which are extremely useful, cannot tell us about the totality of the interaction between the active site and the substrate. In fact, short of inventing experiments that allow one to measure the forces in enzyme active sites it is hard to see how can one use a direct experimental approach to unambiguously correlate the structure and function of enzymes. In fact, in view of the complexity of biological systems it seems that only computers can handle the task of providing a quantitative structure-function correlation.
