Book Description
EPR of Free Radicals in Solids: Trends in Methods and Applications presents methods and applications of modern EPR for the study of free radical processes in solids, which so far are only available in the journal literature. The first part of the book, covering trends in methods, contains experimentally oriented chapters on continuous wave and pulsed EPR techniques and special methods involving muon magnetic resonance and optical detection and theory for dynamic studies. New simulation schemes, including the influence of dynamics, are presented as well as advances in the calculation of hyperfine and electronic g-tensors. The second part of the book presents applications involving studies of radiation and photo-induced inorganic and organic radicals in inert matrices, including novel results of quantum effects in small radicals. High-spin molecules and complexes are also considered as well as radical processes in photosynthesis. Recent advances in EPR dosimetry are summarized.

Book Description
EPR of Free Radicals in Solids: Trends in Methods and Applications, 2nd ed. presents a critical two volume review of the methods and applications of EPR (ESR) for the study of free radical processes in solids. Emphasis is on the progress made in the developments in EPR technology, in the application of sophisticated matrix isolation techniques and in the advancement in quantitative EPR that have occurred since the 1st edition was published. Improvements have been made also at theoretical level, with the development of methods based on first principles and their application to the calculation of magnetic properties as well as in spectral simulations. EPR of Free Radicals in Solids I focuses on the trends in experimental and theoretical methods to extract structural and dynamical properties of radicals and spin probes in solid matrices by continuous wave (CW) and pulsed techniques. It presents simulation techniques and software for CW and pulsed EPR as well as studies of quantum effects at low temperature. The chapters dealing with quantum chemistry methods for the theoretical interpretation of hyperfine coupling tensors and g-tensors have been much extended in this edition and a new chapter on the calculation of zero-field splitting tensors has been added. This new edition is a valuable resource to experimentalists and theoreticians in research involving free radicals, as well as for students of advanced courses in physical chemistry, chemical physics, materials science, biophysics, biochemistry and related fields.

Book Description
Covers the most advanced computational and experimental methods for studying carbon-centered radical intermediates With its focus on the chemistry of carbon-centered radicals and radical cations, this book helps readers fully exploit the synthetic utility of these intermediates in order to prepare fine chemicals and pharmaceutical products. Moreover, it helps readers better understand their role in complex atmospheric reactions and biological systems. Thoroughly up to date, the book highlights the most advanced computational and experimental methods available for studying and using these critically important intermediates. Carbon-Centered Free Radicals and Radical Cations begins with a short history of the field of free radical chemistry, and then covers: A discussion of the relevant theory Mechanistic chemistry, with an emphasis on synthetic utility Molecular structure and mechanism, focusing on computational methods Spectroscopic investigations of radical structure and kinetics, including demonstrations of spin chemistry techniques such as CIDNP and magnetic field effects Free radical chemistry in macromolecules Each chapter, written by one or more leading experts, explains difficult concepts clearly and concisely, with references to facilitate further investigation of individual topics. The authors were selected in order to provide insight into a broad range of topics, including small molecule synthesis, polymer degradation, computational chemistry as well as highly detailed experimental work in the solid, liquid, and gaseous states. This volume is essential for students or researchers interested in building their understanding of the role of carbon-centered radical intermediates in complex systems and how they may be used to develop a broad range of useful products.

Book Description
Distance measurements in biological systems by EPR The foundation for understanding function and dynamics of biological systems is knowledge of their structure. Many experimental methodologies are used for determination of structure, each with special utility. Volumes in this series on Biological Magnetic Resonance emphasize the methods that involve magnetic resonance. This volume seeks to provide a critical evaluation of EPR methods for determining the distances between two unpaired electrons. The editors invited the authors to make this a very practical book, with specific numerical examples of how experimental data is worked up to produce a distance estimate, and realistic assessments of uncertainties and of the range of applicability, along with examples of the power of the technique to answer biological problems. The first chapter is an overview, by two of the editors, of EPR methods to determine distances, with a focus on the range of applicability. The next chapter, also by the Batons, reviews what is known about electron spin relaxation times that are needed in estimating distances between spins or in selecting appropriate temperatures for particular experiments. Albert Beth and Eric Hustedt describe the information about spin-spin interaction that one can obtain by simulating CW EPR line shapes of nitroxyl radicals. The information in fluid solution CW EPR spectra of dual-spin labeled proteins is illustrated by Hassane Mchaourab and Eduardo Perozo.

EPR of Free Radicals in Solids II focuses on the trends in applications of experimental and theoretical methods to extract structural and dynamical properties of radicals and spin probes in solid matrices by continuous wave (CW) and pulsed techniques in nine chapters written by experts in the field. It examines the studies involving radiation- and photo-induced inorganic and organic radicals in inert matrices, the high-spin molecules and metal-based molecular clusters as well as the radical pro-cesses in photosynthesis. Recent advancements in environmental applications in-cluding measurements by myon resonance of radicals on surfaces and by quantitative EPR in dosimetry are outlined and the applications of optical detection in material research with much increased sensitivity reviewed. The potential use of EPR in quantum computing is considered in a newly written chapter. This new edition is aimed to experimentalists and theoreticians in research involving free radicals, as well as for students of advanced courses in physical chemis-try, chemical physics, materials science, biophysics, biochemistry and related fields.
