New Applications Of Electron Spin Resonance

This is the first book covering an interdisciplinary field between microwave spectroscopy of electron paramagnetic resonance (EPR) or electron spin resonance (ESR) and chronology science, radiation dosimetry and ESR (EPR) imaging in material sciences. The main object is to determine the elapsed time with ESR from forensic medicine to the age and radiation dose in earth and space science. This book is written primarily for earth scientists as well as for archaeologists and for physicists and chemists interested in new applications of the method. This book can serve as an undergraduate and graduate school textbook on applications of ESR to geological and archaeological dating, radiation dosimetry and microscopic magnetic resonance imaging (MRI). Introduction to ESR and chronology science and principle of ESR dating and dosimetry are described with applications to actual problems according to materials.

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.

This book describes in mathematical terms the extraction of useful information from ESR spectra as applied to paramagnetic organic, inorganic and organometalic molecules. It lays a firm groundwork for understanding more sophisticated experiments, which the availability of newer commercial instruments has made possible. It takes the reader step by step through obtaining and interpretating ESR spectra of paramagnetic molecules. The mathematical basis of each observed phenomena are detailed and examples given. In particular there is a detailed discussion of 2nd order pertubation theory treatment of the Spin Hamiltonian for non-coincident G and A axes.

This book provides an introduction to the underlying theory, fundamentals, and applications of EPR spectroscopy, as well as new developments in the area. Knowledge of the topics presented will allow the reader to interpret of a wide range of EPR spectra, as well as help them to apply EPR techniques to problem solving in a wide range of areas: organic, inorganic, biological, and analytical chemistry; chemical physics, geophysics, and minerology. Includes updated information on high frequency and multi-frequency EPR, pulsed microwave techniques and spectra analysis, dynamic effects, relaxation phenomena, computer-based spectra simulation, biomedical aspects of EPR, and more Equips readers with sufficient knowledge of EPR techniques to go on in their specialized area of interest Provides problem sets and concise bibliographies at the end of each chapter, plus several tutorial appendices on topics like mathematical operations, quantum mechanics of angular momentum, experimental considerations.

Second edition of classic reference contains comprehensive coverage of experimental techniques, theoretical and practical aspects of ESR instrumentation. Recent developments, plus how to build, use ESR spectrometer. References. 1982 edition.

Electron Spin Resonance in Food Science covers, in detail, the ESR identification of the irradiation history of food products and beverages to investigate changes that occur during storage, with an aim of improving hygienic quality and extending shelf-life with minimal tempering in nutritional profile. The book also includes ESR studies on the interaction of food items and packaging materials, along with a section on new approaches in ESR identification of irradiated foods that is followed by a chapter on international legislation relevant to irradiated food. A section on ESR applications in characterizing ROS/antioxidants in food items and lipid oxidation, including spin labeling, spin trapping and imaging applications is also covered, as are ESR applications in nutrition and pharmaceutics. Serves as a complete reference on the application of ESR spectroscopy in food science research Focuses on applications and data interpretation, avoiding extensive use of mathematics so that it fulfils the need of young scientists from different disciplines Includes informative pages from leading manufacturers, highlighting the features of recent ESR spectrometers used in food science research Includes information on different, active, worldwide groups in ESR characterization of food items and beverages

This book addresses electron spin-qubit based quantum computing and quantum information processing with a strong focus on the background and applications to EPR/ESR technique and spectroscopy. It explores a broad spectrum of topics including quantum computing, information processing, quantum effects in electron-nuclear coupled molecular spin systems, adiabatic quantum computing, heat bath algorithmic cooling with spins, and gateway schemes of quantum control for spin networks to NMR quantum information. The organization of the book places emphasis on relevant molecular qubit spectroscopy. These revolutionary concepts have never before been included in a comprehensive volume that covers theory, physical basis, technological basis, applications, and new advances in this emerging field. Electron Spin Resonance (ESR) Based Quantum Computing, co-edited by leading and renowned researchers Takeji Takui, Graeme Hanson and Lawrence J Berliner, is an ideal resource for students and researchers in the fields of EPR/ESR, NMR and quantum computing. This book also • Explores methods of harnessing quantum effects in electron-nuclear coupled molecular spin systems • Expertly discusses applications of optimal control theory in quantum computing • Broadens the readers’ understanding of NMR quantum information processing
