Available in PDF, EPUB and Kindle. Book excerpt: The development of an area of scientific research is a dynamic process with its own kinetic equations and its own physical mech anism. The study of fast chemical interactions and transformations is such an area, and while it is tempting to draw analogies or to speculate about the simplest model system, the lack of ade quately averaged observables is an annoying obstacle to such an undertaking. Sciences suffering from such conditions usually avoid quantitative models, be they primitive or complex. Instead, they prove their point by "case histories". Chemical relaxation kinetics started as an offspring of research in acoustics. In some aqueous ionic solutions anomalous acoustic absorption had been observed. A systematic study traced the cause of this absorption, showing that the covered frequency range and the intensity of the absorption were related in a predictable manner to the rate at which ions can interact and form structures differing in volume from the non interacting species. The step from this experimental observation and its correct, non trivial explanation to the discovery that all fast chemical pro cesses must reveal themselves quantitatively in the relaxation rate of a perturbed equilibrium state, and that perturbation para meters other than sound waves can be used for its exploitation, was made by MANFRED EIGEN in 1954. The foresightedness of K.F.

Book excerpt: Chemical relaxation spectrometry involves the application of several different relaxation techniques to investigate the kinetics and mechanisms of fast chemical reactions and also dynamic molecul 10 ar processes that occur in liquids in the time range 1 - 10- secs. These methods have been used widely in several disciplines of the natural sciences including molecular biology, biochemistry, organic stereochemistry, detergent chemistry and inorganic chemistry. The purpose of the Advanced Study Institute was to provide a forum for scientists to discuss the role, scope and limitations of the various applications of chemical relaxation methods in order to stimulate discussion and interaction between workers in these different fields. The papers described in this volume are a summary of the contributions that were discussed at the meeting. The brief given to the authors was to attempt to prepare an article contain ing a good supply of references so that the book can be used not only by those starting in the field, but also by the specialist and research worker. These contributions cover a varied range of topics summarizing the achievements, the current state of knowledge and possible application in many disciplines. It is to be hoped that this volume will help to point out some new directions towards which research efforts are required and to attract new researchers with fresh points of view.

Download or read book Molecular Relaxation in Liquids written by Biman Bagchi and published by Oxford University Press. This book was released on 2012-01-30 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book brings together many different relaxation phenomena in liquids under a common umbrella and provides a unified view of apparently diverse phenomena. It aligns recent experimental results obtained with modern techniques with recent theoretical developments. Such close interaction between experiment and theory in this area goes back to the works of Einstein, Smoluchowski, Kramers' and de Gennes. Development of ultrafast laser spectroscopy recently allowed study of various relaxation processes directly in the time domain, with time scales going down to picosecond (ps) and femtosecond (fs) time scales. This was a remarkable advance because many of the fundamental chemical processes occur precisely in this range and was inaccessible before the 1980s. Since then, an enormous wealth of information has been generated by many groups around the world, who have discovered many interesting phenomena that has fueled further growth in this field. As emphasized throughout the book, the seemingly different phenomena studied in this area are often closely related at a fundamental level. Biman Bagchi explains why relatively small although fairly sophisticated theoretical tools have been successful in explaining a wealth of experimental data at a semi-phenomenological level.

Download or read book Relaxation kinetics written by Claude Bernasconi and published by Elsevier. This book was released on 2012-12-02 with total page 301 pages. Available in PDF, EPUB and Kindle. Book excerpt: Relaxation Kinetics focuses on the theory of relaxation kinetics (also known as chemical relaxation) and the experimental techniques used in the study of fast reactions. Topics covered include relaxation times in single-step, two-step, and multistep systems; small perturbations; and relaxation amplitudes in single-step and multistep systems. Chemical relaxation in complex systems is also described, and a complete solution of the relaxation equation is presented. This book is comprised of 16 chapters divided into two sections and begins with an overview of the basic principles of chemical relaxation, including the linearization of rate equations, relaxation times, and transient and stationary relaxation methods. The following chapters explore relaxation times in single-step, two-step, and multistep systems, as well as relaxation amplitudes in single-step and multistep systems. The possibility of linearization of a rate equation for ""small"" perturbations is then considered, along with the derivation of the complete relaxation equation. The next chapter discusses transient relaxation techniques and explains how the data are analyzed for the stationary techniques when dealing with the specific techniques. The second section is devoted to experimental techniques such as the temperature-jump method, the electric field-jump method, and the concentration-jump method. Ultrasonic techniques and stationary electric field methods are also described. This monograph will be a valuable resource for chemists and physicists.
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.
Download or read book Dielectric Relaxation and Dynamics of Polar Molecules written by Vladimir I. Ga?duk and published by World Scientific. This book was released on 1999 with total page 664 pages. Available in PDF, EPUB and Kindle. Book excerpt: The topics covered in this book provide a qualitative and sometimes quantitative classic description of the wide-band 0-THz dielectric spectra of polar liquids, molecular libration-rotation (which is the reason for dielectric loss and absorption of electromagnetic waves), simple molecular models differing by the intermolecular-potential profiles, and present a comparison between the theoretical and experimental dependencies and derivation of the main results. A new feature is the application of a number of analytical models to different substances, including strongly absorbing nonassociating liquids, liquid water, water bound by macromolecules, and gas-like liquids. The presentation of the theory in this book is also new. It is based on the dynamic method in which the Brownian reorientations are considered implicitly, without direct solution of stochastic equations. This approach simplifies the theory. Senior students and experimentalists will find many of the results valuable.
Download or read book Nuclear Spin Relaxation in Liquids written by Jozef Kowalewski and published by CRC Press. This book was released on 2006-03-15 with total page 440 pages. 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.
