Electron Nuclear Double Resonance Spectroscopy of Radicals in Solution. Application to Organic and Biological Chemistry. Methods in Stereochemical Analysis

This book describes the principles of Endor spectroscopy and Triple resonance, with particular emphasis given to applications in organic chemistry and biochemistry. It gives a broad survey of Endor studies of organic and bioorganic radicals in solution, but also discusses in detail special topics such as non–proton Endor, multispin systems, dynamic effects, and Endor spectroscopy using liquid–crystal solvents. Although the authors have adopted a phenomenological presentation for the most part, they also provide a sound theoretical basis. The theoretical concepts and wealth of experimental material presented illustrate the scope and limitations of the different multiple resonance techniques and facilitate finding optimum experimental conditions for a given problem.
