High Resolution NMR in Solids Selective Averaging


Book Description

High Resolution NMR in Solids: Selective Averaging presents the principles and applications of the four approaches to high resolution NMR in solids — magic-angle sample spinning, multiple-pulse, proton-enhanced nuclear induction, and indirect detection methods. Divided into six chapters, this book initially describes the tensorial properties of nuclear spin interactions in both ordinary and spin spaces. It then deals with the manifestations of nuclear magnetic shielding in NMR spectra of both single-crystal and powder samples, and then discusses the techniques for analyzing spectra and rotation patterns in terms of shielding tensors. A wide range of NMR phenomena that are result of intentional or natural, selective or unselective averaging processes and the average Hamiltonian theory that yields the inclusion of correction are covered. This book also provides a detailed discussion on multiple-pulse sequences intended for high resolution NMR in solids. The concluding chapter examines the applications of multiple-pulse techniques, with particular emphasis on measurements of 19F and 1H shielding tensors. Discussions on rotations of angular momentum operators; time ordering and the Magnus expansion; off-resonance averaging of the second-order dipolar Hamiltonian; and phase transients are covered in the supplemental texts.










High Resolution NMR


Book Description

High Resolution NMR: Theory and Chemical Applications discusses the principles and theory of nuclear magnetic resonance and how this concept is used in the chemical sciences. This book is written at an intermediate level, with mathematics used to augment verbal descriptions of the phenomena. This text pays attention to developing and interrelating four approaches – the steady state energy levels, the rotating vector picture, the density matrix, and the product operator formalism. The style of this book is based on the assumption that the reader has an acquaintance with the general principles of quantum mechanics, but no extensive background in quantum theory or proficiency in mathematics is required. This book begins with a description of the basic physics, together with a brief account of the historical development of the field. It looks at the study of NMR in liquids, including high resolution NMR in the solid state and the principles of NMR imaging and localized spectroscopy. This book is intended to assist chemistry graduate students, advanced undergraduate students, or researchers to understand NMR at a fundamental level. This text also provides illustrations of the applications of NMR to the determination of the structure of small organic molecules and macromolecules, including proteins.

Gas Phase NMR


Book Description

This book covers the recent NMR studies with the application of gaseous molecules. Among the comprehensively discussed aspects of the area it includes in particular: new multinuclear experiments that deliver spectral parameters of isolated molecules and provide the most accurate values of nuclear magnetic shielding, isotropic spin–spin coupling and relaxation times; advanced, precise and correct theoretical descriptions of spectral parameters of molecules as well as the application of gas-phase NMR measurements to chemical analysis and medicine. The progress of research in these fields is enormous and has rapidly changed our knowledge and understanding of molecular parameters in NMR spectroscopy. For example, accurate studies of the shielding for isolated molecules allow the exact determination of nuclear magnetic dipole moments, the calculated values of spectral parameters can be verified by precise gas-phase NMR measurements, and the application of hyperpolarized noble gases provides excellent MRI pictures of lungs. Aimed at graduates and researchers in spectroscopy, analytical chemistry and those researching the applications of NMR in medicine, this book presents the connections between sophisticated experiments, the theory of magnetic parameters and the exploration of new methods in practice.




Principles of Magnetic Resonance


Book Description

The first edition of this book was written in 1961 when I was Morris Loeb Lecturer in Physics at Harvard. In the preface I wrote: "The problem faced by a beginner today is enormous. If he attempts to read a current article, he often finds that the first paragraph refers to an earlier paper on which the whole article is based, and with which the author naturally assumes familiarity. That reference in turn is based on another, so the hapless student finds himself in a seemingly endless retreat. I have felt that graduate students or others beginning research in magnetic resonance needed a book which really went into the details of calculations, yet was aimed at the beginner rather than the expert. " The original goal was to treat only those topics that are essential to an understanding of the literature. Thus the goal was to be selective rather than comprehensive. With the passage of time, important new concepts were becoming so all-pervasive that I felt the need to add them. That led to the second edition, which Dr. Lotsch, Physics Editor of Springer-Verlag, encouraged me to write and which helped launch the Springer Series in Solid-State Sciences. Now, ten years later, that book (and its 1980 revised printing) is no longer available. Meanwhile, workers in magnetic resonance have continued to develop startling new insights.




Perspectives on Solid State NMR in Biology


Book Description

Solid state NMR is rapidly emerging as a universally applicable method for the characterization of ordered structures that cannot be studied with solution methods or diffraction techniques. This proceedings -; from a recent international workshop - captures an image of the latest developments and future directions for solid state NMR in biological research, particularly on membrane proteins. Detailed information on how hormones or drugs bind to their membrane receptor targets is needed, e.g. for rational drug design. Higher fields are bringing clear improvements, and the power of solid state NMR techniques for studying amorphous and membrane associated peptides, proteins and complexes is shown by examples of applications at ultra-high fields. Progress in protein expression, experimental design and data analysis are also presented by leaders in these research areas.
