Book Description
Since the first successful NMR experiments in 1946 it was well appreciated that dynamic processes play an important role in the NMR spectroscopy of bulk matter [1]. Early theories on the dependence of the relaxation parameters Tl and T2 on the motions of nuclear spins were successful in explaining the dipolar broadening of the NMR signal in solids and the motional narrowing in liquids [2]. With the discovery of chemical shifts and spin-spin couplings another type of dynamical process affect ing the NMR line shape became apparent, the chemical exchange. As a consequence, dynamical NMR studies split into two groups differing not only in the dynamical topics but also in the method of investigation: physical studies of the motion of spins in liquids and solids by measurement of the relaxation times of single resonances and, on the other hand, chemical studies based on band shape analysis of NMR spectra recorded under steady state conditions. The two fields of research lost some of their basic differences with the development of the Fourier transform NMR method [3], which allows the measurement of relaxation times of different resonances at the same time, i. e. the study of differential motional behavior of different parts of mole cules, thus providing a new tool in conformational analyses. For example, informa tion can be obtained by this method on the relative importance of overall motions and internal motions [4].

Book Description
Spin Dynamics: Basics of Nuclear Magnetic Resonance, Second Edition is a comprehensive and modern introduction which focuses on those essential principles and concepts needed for a thorough understanding of the subject, rather than the practical aspects. The quantum theory of nuclear magnets is presented within a strong physical framework, supported by figures. The book assumes only a basic knowledge of complex numbers and matrices, and provides the reader with numerous worked examples and exercises to encourage understanding. With the explicit aim of carefully developing the subject from the beginning, the text starts with coverage of quarks and nucleons and progresses through to a detailed explanation of several important NMR experiments, including NMR imaging, COSY, NOESY and TROSY. Completely revised and updated, the Second Edition features new material on the properties and distributions of isotopes, chemical shift anisotropy and quadrupolar interactions, Pake patterns, spin echoes, slice selection in NMR imaging, and a complete new chapter on the NMR spectroscopy of quadrupolar nuclei. New appendices have been included on Euler angles, and coherence selection by field gradients. As in the first edition, all material is heavily supported by graphics, much of which is new to this edition. Written for undergraduates and postgraduate students taking a first course in NMR spectroscopy and for those needing an up-to-date account of the subject, this multi-disciplinary book will appeal to chemical, physical, material, life, medical, earth and environmental scientists. The detailed physical insights will also make the book of interest for experienced spectroscopists and NMR researchers. • An accessible and carefully written introduction, designed to help students to fully understand this complex and dynamic subject • Takes a multi-disciplinary approach, focusing on basic principles and concepts rather than the more practical aspects • Presents a strong pedagogical approach throughout, with emphasis placed on individual spins to aid understanding • Includes numerous worked examples, problems, further reading and additional notes Praise from the reviews of the First Edition: "This is an excellent book... that many teachers of NMR spectroscopy will cherish... It deserves to be a ‘classic’ among NMR spectroscopy texts." NMR IN BIOMEDICINE "I strongly recommend this book to everyone...it is probably the best modern comprehensive description of the subject."

Book Description
Addresses Dynamic Nuclear Polarization (DNP) as a technique for sensitivity-enhancement in solid-state NMR spectroscopy This comprehensive handbook is a compendium of the current state-of-the art of high field Dynamic Nuclear Polarization—from long-proven, early developments, up to today’s hot topics. It covers all the relevant subjects that have made a direct or indirect contribution toward advancing this field, and focuses on topics such as: the theory behind the effects seen within DNP; instrumentation required for carrying out DNP; and specific applications of DNP including protein monitoring, catalysis, nanoparticles, biological and clinical studies. Development and application of techniques that have indirectly contributed to advancing MAS DNP NMR, such as DNP experiments on static solids within microwave resonant structures, and high-field EPR, are also examined. Handbook of High Field Dynamic Nuclear Polarization is presented in three sections—Theoretical Aspects, DNP Development (instrumentation / radical / sample), and DNP NMR Applications. The first section offers chapters on; solid and cross effect DNP; thermal mixing; Overhauser; and dissolution DNP. The second looks at: microwave technology, gyrotron, and IOE; homebuilt and commercial DNP spectrometers; and glassing vs. solvent-free DNP. The final section provides information on; amyloid, membrane, and nanocrystalline proteins; metals, and surface enhanced DNP; pharmaceuticals; nanoparticles; and much more. Covers one of the biggest developing fields in magnetic resonance Relevant to students, academics, and industry within the physical, materials, medical, and biochemical sciences An excellent starting point and point-of-reference for researchers in the field Edited by a widely respected team with contributions from key researchers in the NMR community Part of the eMagRes Handbook Series Handbook of High Field Dynamic Nuclear Polarization is an ideal reference for all researchers and graduate students involved in this complex, interdisciplinary field.

Book Description
Nuclear magnetic resonance (NMR) spectroscopy is one of the most powerful and widely used techniques in chemical research for investigating structures and dynamics of molecules. Advanced methods can even be utilized for structure determinations of biopolymers, for example proteins or nucleic acids. NMR is also used in medicine for magnetic resonance imaging (MRI). The method is based on spectral lines of different atomic nuclei that are excited when a strong magnetic field and a radiofrequency transmitter are applied. The method is very sensitive to the features of molecular structure because also the neighboring atoms influence the signals from individual nuclei and this is important for determining the 3D-structure of molecules. This new edition of the popular classic has a clear style and a highly practical, mostly non-mathematical approach. Many examples are taken from organic and organometallic chemistry, making this book an invaluable guide to undergraduate and graduate students of organic chemistry, biochemistry, spectroscopy or physical chemistry, and to researchers using this well-established and extremely important technique. Problems and solutions are included.
