Download or read book Cross relaxation and Cross correlation Parameters in NMR written by Daniel Canet and published by Royal Society of Chemistry. This book was released on 2017-10-18 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Nuclear magnetic resonance (NMR) is widely used across many fields because of the rich data it produces, and some of the most valuable data come from the study of nuclear spin relaxation in solution. While described to varying degrees in all major NMR books, spin relaxation is often perceived as a difficult, if not obscure, topic, and an accessible, cohesive treatment has been nearly impossible to find. 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, and the level of detail is somewhat greater than most other NMR texts. Topics include cross-relaxation, multispin phenomena, relaxation studies of molecular dynamics and structure, and special topics such as relaxation in systems with quadrupolar nuclei and paramagnetic systems. Avoiding overly demanding mathematics, the authors explain relaxation in a manner that anyone with a basic familiarity with NMR can follow, regardless of their specialty. The focus is on illustrating and explaining the physical nature of the phenomena, rather than the intricate details. Nuclear Spin Relaxation in Liquids: Theory, Experiments, and Applications forms useful supplementary reading for graduate students and a valuable desk reference for NMR spectroscopists, whether in chemistry, physics, chemical physics, or biochemistry.

Download or read book NMR as a Structural Tool for Macromolecules written by M.D. Kemple and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: The contemplation of truth and beauty is the proper object for which we were created, which calls forth the most intense desires of the soul, and of which it never tires -Hazlitt In his Nobel lecture Purcell commented that when he saw snow in New England after the discovery of NMR, it appeared like "heaps of protons quietly precessing in earth's magnetic field. " If he were to make the comment in the context of how NMR is being used today, he could have conjured up an image of hydrogen, carbon, and nitrogen nuclei in proteins of an earthbound 8rganism subtly orchestrating a quiet symphony of frequencies, from 150 Hz to 2 kHz, carrying clues to the three-dimensional structure of the macromolecules. The manner in which the basic discoveries of Bloch and Purcell have led to the emergence of NMR, several decades later, as a major technique of biological and medical physics (and chemistry) is a striking example of the power of basic research. It is also a fascinating saga whereby whenever it was felt that the field had reached a plateau, new directions, new technologies, and sometimes serendipity produced new developments that revolutionized the technique and enhanced its capability. As Richard Ernst points out "NMR is intellectually attractive, . . . the practical importance of NMR is enormous, and can justify much of the playful activities of an addicted spectroscopist" (Nobel lecture).

Download or read book Long lived Nuclear Spin Order written by Giuseppe Pileio and published by Royal Society of Chemistry. This book was released on 2020-04-07 with total page 462 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book BioNMR in Drug Research written by Oliver Zerbe and published by John Wiley & Sons. This book was released on 2006-03-06 with total page 502 pages. Available in PDF, EPUB and Kindle. Book excerpt: The vast progress made in the investigation of biomolecules using NMR has only recently been rewarded with the Nobel Prize for Kurt Wüthrich. Edited by a former coworker of Wüthrich, this book presents the theoretical background on NMR of biomolecules, plus the use of NMR techniques in determining the structures of proteins and nucleic acids. BioNMR spectroscopy offers a universal tool for examining the binding of an active substance to its target protein. Its use thereby benefits the rational development of drugs. This interaction can now be investigated in a hitherto unparalleled precision and displayed in 3D - an important prerequisite for the targeted development of new active substances. The latest methods for characterizing substance-receptor complexes are demonstrated backed by many case studies from pharmaceutical research. Thus it comes as no surprise that a large number of the authors are working for leading pharmaceutical companies. With its successful mixture of basic information and application strategies, coupled with many real-life examples, this is an invaluable guide for both NMR spectroscopists and pharmaceutical researchers.
Download or read book Methodological Developments In NMR Using Cross correlations And Spatial Encoding written by and published by . This book was released on 2002 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis aims at the methodological developments in Nuclear Magnetic Resonance (NMR). The methodological developments in NMR has a long and successful history. The present thesis attempts to contribute some novel methods in this direction. This thesis restricts itself to two methodological developments, namely, (1) effects of cross-correlations between the chemical shift anisotropy (CSA) and dipole-dipole interactions in the relaxation of various nuclei and experiments which utilize spatial encoding. The cross-correlation has been successfully utilized to investigate the anisotropic motions of liquid crystals, and to understand the chemical shift anisotropy of fluorine atoms of Fluorine substituted ring compounds. Spatial encoding schemes have been developed to facilitate single scan measurements of longitudinal spin lattice relaxation times and implementations of parallel search algorithms.

Download or read book Encyclopedia of Biophysics written by Gordon Roberts and published by Springer. This book was released on 2012-10-08 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Encyclopedia of Biophysics is envisioned both as an easily accessible source of information and as an introductory guide to the scientific literature. It includes entries describing both Techniques and Systems. In the Techniques entries, each of the wide range of methods which fall under the heading of Biophysics are explained in detail, together with the value and the limitations of the information each provides. Techniques covered range from diffraction (X-ray, electron and neutron) through a wide range of spectroscopic methods (X-ray, optical, EPR, NMR) to imaging (from electron microscopy to live cell imaging and MRI), as well as computational and simulation approaches. In the Systems entries, biophysical approaches to specific biological systems or problems – from protein and nucleic acid structure to membranes, ion channels and receptors – are described. These sections, which place emphasis on the integration of the different techniques, therefore provide an inroad into Biophysics from a biological more than from a technique-oriented physical/chemical perspective. Thus the Encyclopedia is intended to provide a resource both for biophysicists interested in methods beyond those used in their immediate sub-discipline and for those readers who are approaching biophysics from either a physical or biological background.

This book was released on 2014-05-08 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nicola Salvi's thesis offers a remarkably cogent view of highly sophisticated NMR methods. Salvi developed these methods in order to characterize the amplitudes and frequency ranges of local motions in biomolecules such as proteins. These local motions play an essential role since they can explain many of the remarkable properties of proteins and enable them to carry out all sorts of vital functions, from enzymatic catalysis to intermolecular recognition and signalling in cells. Salvi's work has led to numerous publications in high-impact journals.

Download or read book Fluctuations Diffusion and Spin Relaxation written by R. Lenk and published by Elsevier Publishing Company. This book was released on 1986 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is well known that NMR is an excellent tool for the study of those molecular systems that are characterized by a great number of spatial configurations, high entropy and the presence of significant random movements, such as liquids, polymers and biological cellular systems. The aim of this book is to introduce some new ideas to the subject. The book is theoretical and conceptual in character. It has grown out of lectures given by the author on general physiology and the elements of biophysics, and from his lectures and seminars given at, among others, the Congresses of the European Society of NMR in Biology and Medicine. The information is presented in six chapters and follows a logical development of the subject. The probabilistic and statistical fundamentals are first introduced. The theory of spin relaxation is derived from the classical and quantum theory of linear irreversibility. Diffusion and flow are treated here with particular application to living systems such as the NMR blood flow-meters, flow imaging, the dynamics and order in water systems of plants and tumors.
