Index. décimale : |
B-B |
Résumé : |
"Focusing primarily on isolated paramagnetic species, Electron Paramagnetic Resonance is designed to provide senior undergraduate and graduate students as well as professionals with the essential understanding needed to use this technique and be active in various specialized fields of interest.
Electron Paramagnetic Resonance enables those with no previous background in quantum mechanics to gain a fundamental grasp of EPR. It helps those with moderate training to acquire more sophisticated mathematical and quantum-mechanical skills and a knowledge of powerful theoretical and experimental techniques—tools that will allow them to interpret a wide range of EPR spectra.
This important work also introduces many exciting new EPR developments in progress, including time-resolved spectroscopy, which involves the acquisition of EPR data for short-lived species. In addition, it highlights the increasing complexity of the experimental equipment currently used, including spectrometers that operate both in the classical continuous-wave mode and in pulsed mode. This book also discusses how computers can direct spectrometer control and data acquisition, analyze data to yield to underlying parameters, and produce accurate simulated spectra.
Readers will acquire a heightened historical appreciation of the EPR technique, discovering how EPR studies have:
* confirmed the existence of triplet states, establishing that new adsorption bands observed in optical spectra following excitation by light of certain molecules arise from the unpairing of electron spins
* identified chlorophyll radicals as the primary donor in the photosynthesis process, as well as other key intermediates in this reaction
* clarified the structure and function of systems of biomedical interest, including oxygen carriers and various enzymes
* uncovered paramagnetic species in insulators and semiconductors and described their environment
* facilitated chemists' investigation of reaction mechanisms." |

B-B |
Résumé : |
"This book is intended to collect in one place as much information as possible on the use of EPR spectroscopy in the analysis of systems in which two or more spins are magnetically coupled. This is a field where research is very active and chemists are elbow-to-elbow with physicists and biologists in the forefront. Here, as in many other fields, the contributions coming from different disciplines are very important, but for active researchers it is sometimes difficult to follow the literature, due to differences in languages, and sources which are familiar to, e. g. , a physicist, are exotic to a chemist. Therefore, an effort is needed in order to provide a unitary description of the many different phenomena which are collected under the title. In order to define the arguments which are treated, it is useful to state clearly what is not contained here. So we do not treat magnetic phenomena in conductors and we neglect ferro- and antiferromagnetic resonance. The basic foundations of EPR spectroscopy are supposed to be known by the reader, while we introduce the basis of magnetic interactions between spins. In the first two chapters we review the foundations of exchange interactions, trying to show how the magnetic parameters are bound to the electronic structure of the interacting centers." |

ELECTRON PARAMAGNETIC RESONANCE SPECTROSCOPY |
Résumé : |
"In the twenty-five years since its discovery by Zavoiskii, the technique of electron spin resonance (ESR) spectroscopy has provided detailed struc tural information on a variety of paramagnetic organic and inorganic sys tems. It is doubtful that even much later than 1945 any chemist would have been so bold as to predict the great diversity of systems which have proved amenable to study by ESR spectroscopy. In this book we have attempted to provide numerous examples of actual ESR spectra to illus trate the wide scope of application. No attempt has been made to present a comprehensive coverage of the literature in any field, but references to reviews and key articles are given throughout the book. This introductory textbook had its origin in lecture notes prepared for an American Chemical Society short course on electron spin resonance. The present version is the result of extensive revision and expansion of the original notes. Experience with such courses has convinced us that there are large numbers of chemists, physicists, and biologists who have a strong interest in electron spin resonance. The mathematical training of most of the short-course students is limited to calculus. Their contact with theories of molecular structure is largely limited to that obtained in an elementary physical chemistry course. It is to an audience of such background that this book is directed." |

ELECTRON PARAMAGNETIC RESONANCE SPECTROSCOPY SPIN EXCHANGE |
Index. décimale : |
B-B |
Résumé : |
"Spin exchange between paramagnetic particles is one of the few elementary bimolecular processes in solutions that is readily accessible to detailed experimental studies and to strict theoretical description. Due to this fact spin exchange is now widely used in solving various problems of chemistry, physics, and molecular biology. Spin exchange allows one to study in detail elementary acts of collisions of molecules. By use of spin exchange one can obtain quantitative information on collision rates of molecules in solutions, steric hinderance in collisions, electrostatic interactions in collisions of charged particles, and overlap of electron orbitals in collisions. Par ticularly valuable is the possibility of using spin exchange to study col lisions in such complex systems as polymer solutions, multicomponent mix tures, heterogeneous mixtures, and especially biological systems. This monograph contains a comprehensive description of spin exchange in solutions. It consists of four chapters. The introductory chapter contains a brief summary of the physical principles of spin exchange and outlines the range of its main applications. In this chapter a historic background of research in this field is also given. The second chapter contains a com prehensive presentation of the theory of spin exchange including that of its spectroscopic manifestations. The third chapter is devoted to a detailed description of the technique of experimental studies of spin exchange. The last - the fourth - chapter summarizes the results of experimental studies of spin exchange and considers various applications of spin exchange in che mistry, molecular physics, and biology." |
