Book Description
Nuclear magnetic resonance (NMR) is widely used across many fields of science because of the rich data it produces, and some of the most valuable data come from studies of nuclear spin relaxation in solution. The first edition of this book, published more than a decade ago, provided an accessible and cohesive treatment of the field. The present second edition is a significant update, covering important new developments in recent years. Collecting relaxation theory, experimental techniques, and illustrative applications into a single volume, this book clarifies the nature of the phenomenon, shows how to study it and explains why such studies are worthwhile. Coverage ranges from basic to rigorous theory and from simple to sophisticated experimental methods. Topics include cross-relaxation, multispin phenomena, relaxation studies of molecular dynamics and structure and special topics such as relaxation in systems with quadrupolar nuclei, in paramagnetic systems and in long-living spin states. Avoiding overly demanding mathematics, the authors explain spin relaxation in a manner that anyone with a familiarity with NMR can follow. The focus is on illustrating and explaining the physical nature of relaxation phenomena. Nuclear Spin Relaxation in Liquids: Theory, Experiments and Applications, 2nd edition, provides useful supplementary reading for graduate students and is a valuable reference for NMR spectroscopists, whether in chemistry, physics or biochemistry.

Book Description
This book deals with spin relaxation by underlying the similarities between nuclear and electron spins, and provides a clear and unified picture of the behavior of spins in magnetic resonance. It is especially tailored for scientists dealing with chemical applications of relaxation phenomena. It reviews the basic theory together with the mathematical approach and shows how the theory elucidates the structure and dynamic behavior of transition metal complexes, metal clusters and metalloproteins. The complete theory of contrast agents in magnetic resonance imaging is also presented. The book is a unique and valuable guide for anyone working with paramagnetic systems, from physical and inorganic chemists to biophysicists.

Book Description
The Nuclear Overhauser Effect aims to provide a unified treatment of both the theory and applications of the NOE that would be accessible to the chemist who is not a specialist in NMR, but who would nevertheless like to use the NOE to solve problems in his own area of interest. Assuming only that the reader has a typical chemist's working knowledge of NMR, an attempt is made to present the results in each section in a sufficiently simple form so that little mathematical sophistication will be required to apply them with understanding. This book comprises eight chapters, and begins with a focus on nuclear spin-lattice relaxation. The following chapters then discuss mechanisms of spin-lattice relaxation; the nuclear overhauser effect in rigid molecules; the effects of internal motions; experimental methods; transient methods; the effects of chemical exchange; and applications of the nuclear overhauser effect, with a review of available literature. This book will be of interest to practitioners in the fields of chemistry and physics.

Book Description
Spin relaxation parameters, although difficult to interpret, are attracting interest in NMR as these parameters are capable of yielding both structural and dynamic information. Cross-relaxation and cross-correlation parameters afford a non-ambiguous approach to molecular structure and dynamics although they require some special skills for their experimental determination and for their exploitation. This work will start with an introduction to nuclear spin cross-relaxation and cross-correlation phenomena in liquids then look in more detail at molecules in soft matter and large biomolecules. Providing a detailed, timely account, the authors are filling a gap in the present NMR literature for the analytical scientist.

Book Description
A detailed derivation of the equations governing dynamic nuclear polarization (DNP) and nuclear spin-lattice relaxation by use of the spin-temperature theory has been carried to second order in a perturbation expansion of the density matrix. Nuclear spin diffusion in the rapid diffusion limit and the effects of the coupling of the electron dipole-dipole reservoir (EDDR) with the nuclear spins are incorporated. The complete expression for the dynamic nuclear polarization has been derived and then examined in detail for the limit of well-resolved solid-effect transitions. Exactly at the solid-effect transition peaks, the conventional solid-effect DNP results are obtained, but with EDDR effects on the nuclear relaxation and DNP leakage factor included. Explicit EDDR contributions to DNP are discussed, and a new DNP effect is predicted.

Book Description
The idea that a long-lived form of spin order, namely singlet order, can be prepared from nuclear spin magnetisation first emerged in 2004. The unusual properties of singlet order–its long lifetime and the fact that it is NMR silent but interconvertible into other forms of NMR active order—make it a ‘smart tag’ that can be used to store information for a long time or through distant space points. It is not unexpected then, that since its first appearance, this idea has caught the attention of research groups interested in exploiting this form of order in different fields of research spanning from biology to materials science and from hyperpolarisation to quantum computing. This first book on the subject gives a thorough description of the various aspects that affect the development of the topic and details the interdisciplinary applications. The book starts with a section dedicated to the basic theories of long-lived spin order and then proceeds with a description of the state-of-the-art experimental techniques developed to manipulate singlet order. It then concludes by covering the generalization of the concept of singlet order by introducing and discussing other forms of long-lived spin order.
