Electron Paramagnetic Resonance Spectroscopy by Patrick Bertrand Pdf

Although originally invented and employed by physicists, electron paramagnetic resonance (EPR) spectroscopy has proven to be a very efficient technique for studying a wide range of phenomena in many fields, such as chemistry, biochemistry, geology, archaeology, medicine, biotechnology, and environmental sciences. Acknowledging that not all studies require the same level of understanding of this technique, this book thus provides a practical treatise clearly oriented toward applications, which should be useful to students and researchers of various levels and disciplines. In this book, the principles of continuous wave EPR spectroscopy are progressively, but rigorously, introduced, with emphasis on interpretation of the collected spectra. Each chapter is followed by a section highlighting important points for applications, together with exercises solved at the end of the book. A glossary defines the main terms used in the book, and particular topics, whose knowledge is not required for understanding the main text, are developed in appendices for more inquisitive readers.

Electron Paramagnetic Resonance of d Transition Metal Compounds by F.E. Mabbs,D. Collison Pdf

Electron paramagnetic resonance (epr) spectroscopy is a sensitive and versatile method of studying paramagnets, which is finding increasing use in chemistry, biochemistry, earth and materials sciences. The technique is treated both qualitatively and quantitatively, with a progressive increase in sophistication in each succeeding chapter. Following a general introductory chapter, the first half of the book deals with single unpaired electron systems and considers both metal and ligand Zeeman, hyperfine and quadrupole interactions. The simulation of these spectra is discussed, followed by the relationship between spin-Hamiltonian parameters and models of the electronic structures of paramagnets. The second half of the book treats multiple unpaired electron systems using the same philosophy. An introduction to the epr properties of cluster compounds and of extended exchanging systems is also given. There is a chapter on linewidths and lineshapes, and an extensive appendix containing much additional information. A wide-ranging library of simulated and experimental spectra is given, as well as graphical data which should aid spectrum interpretation. Each chapter contains key references and there is a substantial subject and keyword index. This book is designed to teach epr spectroscopy to students without any previous knowledge of the technique. However, it will also be extremely useful to researchers dealing with paramagnetic d transition metals.

Electron Paramagnetic Resonance of Exchange Coupled Systems by Alessandro Bencini,Dante Gatteschi Pdf

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.

Spin-Label Electron Paramagnetic Resonance Spectroscopy by Derek Marsh Pdf

Spin-label electron paramagnetic resonance (EPR) spectroscopy is a versatile molecular probe method that finds wide application in molecular biophysics and structural biology. This book provides the first comprehensive summary of basic principles, spectroscopic properties, and use for studying biological membranes, protein folding, supramolecular structure, lipid-protein interactions, and dynamics. The contents begin with discussion of fundamental theory and practice, including static spectral parameters and conventional continuous-wave (CW) spectroscopy. The development then progresses, via nonlinear CW-EPR for slower motions, to the more demanding time-resolved pulse EPR, and includes an in-depth treatment of spin relaxation and spectral line shapes. Once the spectroscopic fundamentals are established, the final chapters acquire a more applied character. Extensive appendices at the end of the book provide detailed summaries of key concepts in magnetic resonance and chemical physics for the student reader and experienced practitioner alike. Key Features: Indispensable reference source for the understanding and interpretation of spin-label spectroscopic data in its different aspects. Tables of fundamental spectral parameters are included throughout. Forms the basis for an EPR graduate course, extending up to a thorough coverage of advanced topics in Specialist Appendices. Includes all necessary theoretical background. The primary audience is research workers in the fields of molecular biophysics, structural biology, biophysical chemistry, physical biochemistry and molecular biomedicine. Also, physical chemists, polymer physicists, and liquid-crystal researchers will benefit from this book, although illustrative examples used are often taken from the biomolecular field. Readers will be postgraduate researchers and above, but include those from other disciplines who seek to understand the primary spin-label EPR literature.

Biomolecular EPR Spectroscopy by Wilfred Raymond Hagen Pdf

Comprehensive, Up-to-Date Coverage of Spectroscopy Theory and its Applications to Biological Systems Although a multitude of books have been published about spectroscopy, most of them only occasionally refer to biological systems and the specific problems of biomolecular EPR (bioEPR). Biomolecular EPR Spectroscopy provides a practical introduction to bioEPR and demonstrates how this remarkable tool allows researchers to delve into the structural, functional, and analytical analysis of paramagnetic molecules found in the biochemistry of all species on the planet. A Must-Have Reference in an Intrinsically Multidisciplinary Field This authoritative reference seamlessly covers all important bioEPR applications, including low-spin and high-spin metalloproteins, spin traps and spin lables, interaction between active sites, and redox systems. It is loaded with practical tricks as well as do’s and don’ts that are based on the author’s 30 years of experience in the field. The book also comes with an unprecedented set of supporting software designed with simple graphical user interfaces that allow readers to tackle problems they will likely encounter when engaged in spectral analysis. Breaking with convention, the book broaches quantum mechanics from the perspective of biological relevance, emphasizing low-symmetry systems. This is a necessary approach since paramagnets in biomolecules typically have no symmetry. Where key topics related to quantum mechanics are addressed, the book offers a rigorous treatment in a style that is quick-to-grasp for the non expert. Biomolecular EPR Spectroscopy is a practical, all-inclusive reference sure to become the industry standard.

Electron Spin Resonance by John Wertz Pdf

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 unique, self-contained resource is the first volume on electron paramagnetic resonance (EPR) spectroscopy in the eMagRes Handbook series. The 27 chapters cover the theoretical principles, the common experimental techniques, and many important application areas of modern EPR spectroscopy. EPR Spectroscopy: Fundamentals and Methods is presented in four major parts: A: Fundamental Theory, B: Basic Techniques and Instrumentation, C: High-Resolution Pulse Techniques, and D: Special Techniques. The first part of the book gives the reader an introduction to basic continuous-wave (CW) EPR and an overview of the different magnetic interactions that can be determined by EPR spectroscopy, their associated theoretical description, and their information content. The second provides the basics of the various EPR techniques, including pulse EPR, and EPR imaging, along with the associated instrumentation. Parts C and D builds on parts A and B and offer introductory accounts of a wide range of modern advanced EPR techniques, with examples of applications. The last two parts presents most of the new advances that do not appear in most of the classical EPR textbooks that focus on CW EPR. EPR Spectroscopy: Fundamentals and Methods contains, in concise form, all the material needed to understand state-of-the-art EPR spectroscopy at the graduate school/research level, whilst the editors have ensured that it presents the topic at a level accessible to newcomers to the field and others who want to know its range of application and how to apply it.

Quantitative EPR by Gareth R. Eaton,Sandra S. Eaton,David P. Barr,Ralph T. Weber Pdf

There is a growing need in both industrial and academic research to obtain accurate quantitative results from continuous wave (CW) electron paramagnetic resonance (EPR) experiments. This book describes various sample-related, instrument-related and software-related aspects of obtaining quantitative results from EPR expe- ments. Some speci?c items to be discussed include: selection of a reference standard, resonator considerations (Q, B ,B ), power saturation, sample position- 1 m ing, and ?nally, the blending of all the factors together to provide a calculation model for obtaining an accurate spin concentration of a sample. This book might, at ?rst glance, appear to be a step back from some of the more advanced pulsed methods discussed in recent EPR texts, but actually quantitative “routine CW EPR” is a challenging technique, and requires a thorough understa- ing of the spectrometer and the spin system. Quantitation of CW EPR can be subdivided into two main categories: (1) intensity and (2) magnetic ?eld/mic- wave frequency measurement. Intensity is important for spin counting. Both re- tive intensity quantitation of EPR samples and their absolute spin concentration of samples are often of interest. This information is important for kinetics, mechanism elucidation, and commercial applications where EPR serves as a detection system for free radicals produced in an industrial process. It is also important for the study of magnetic properties. Magnetic ?eld/microwave frequency is important for g and nuclear hyper?ne coupling measurements that re?ect the electronic structure of the radicals or metal ions.
