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.

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 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.

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.

Electron paramagnetic resonance (EPR) spectroscopy has been widely used for more than 60 years. However, in recent years, EPR spectroscopy has expanded significantly in the field of practical applications, mainly due to its advantages, such as its high sensitivity (to 1012-1013 molecules, which translates to 10-11 to 10-12 M) and selectivity (only for paramagnetic species). Moreover, it is a quick, non-destructive method, and in some cases, samples may be kept as documents for future inspection. The design of portable EPR spectrometers with small dimensions greatly facilitates the use of this method in practice. The aim of the Special Issue "Applied EPR spectroscopy" is to highlight the current status as well as trends in the development and application of EPR spectroscopy. It covers EPR research in the fields of biology and medicine, chemistry (metal complexes, polymers, and catalysis), dosimetry, geology, mineralogy, archaeology, environmental control, food technology, quantitative EPR, etc.

Computational and Instrumental Methods in EPR is devoted to both instrumentation and computation aspects of EPR, while addressing applications such as spin relaxation time measurements. However, this is the first comprehensive volume to offer practical, non-invasive spectroscopic methods of analyzing the rheology of biopolymers: comparative studies of polymer fluidity using traditional methods (e.g. viscosity) and nuclear magnetic resonance.

Since its inception 50 years ago, electron paramagnetic resonance (EPR, also called ESR or EMR) has become a major tool in diverse fields ranging from biology and chemistry to solid state physics and materials science. This important book includes personal descriptions of early experiments by pioneers who laid the foundations for the field, perspectives on the state of the art, and glimpses of future opportunities. It presents a broad view of the foundations of EPR and its applications, and will therefore appeal to scientists in many fields. Even the expert will find here history not previously recorded and provocative views of future directions.
