Book Description
In the short time since the first nitroxyl radical was obtained in 1959, a new branch of chemical science has arisen and taken shape-the chemistry of stable nitroxyl radicals. The present book was written by E. G. Rozantsev, one of the pioneers in this field and a prominent specialist on stable radicals at the Division of Chemical and Biological Processes of the Institute of Chemical Physics, Academy of Sciences of the USSR. His numerous papers have contributed greatly to the present situation, wherein nitroxyl radicals have acquired unusually wide popularity, including the fields of biology, medicine, chemis try, physics, biophysics, and instrument construction. A clear illustration of the astonishingly vigorous development of this new field of chemistry can be given by the enormous flow of information on the synthesis and use of nitroxyl radicals. There is no doubt that this monograph, which in part generalizes the results of many workers studying these radicals, will be received with interest by specialists working in this field. The author has not attempted to give an exhaustive account of the material. His aim is to introduce the reader to this new field and to show the wide possibilities for using radicals in scientific experiment. The voluminous bibliography, including many papers by the author himself which may not be well enough known to the American reader, will undoubtedly contribute to the usefulness of the monograph.

Book Description
Nitroxides are versatile small organic molecules possessing a stabilised free radical. With their unpaired electron spin they display a unique reactivity towards various environmental factors, enabling a diverse range of applications. They have uses as synthetic tools, such as catalysts or building blocks; imaging agents and probes in biomedicine and materials science; for medicinal antioxidant applications; and in energy storage. Polynitroxides (polymers bearing pendant nitroxide sidechains) have been used in organic radical batteries, oxidation catalysts and in exchange reactions for constructing complex architectures. Chapters in this book cover the synthesis of nitroxides, EPR studies and magnetic resonance applications, physiochemical studies, and applications including in batteries, imaging and organic synthesis. With contributions from leaders in the field, Nitroxides will be of interest to graduate students and researchers across chemistry, physics, biology and materials science.

Book Description
The purpose of the present series of publications is two-fold. In the first place it is intended to review progress in the development of practical stabilising systems for a wide range of polymers and applications. A complementary and ultimately more important objec tive is to accommodate these practical developments within the framework of antioxidant theory, since there can be little question that further major advances in the practice of stabilisation technology will only be possible on the basis of a firm mechanistic foundation. Research into the role of 'stable' free radicals as antioxidants and stabilisers for polymers has intensified in recent years. Nitroxyl radicals (nitroxides) were the earliest long-lived radicals to be investi gated in detail and Maslov and Zaikov review the developments that have taken place in understanding their reaction mechanisms from the time when they were first investigated in liquid hydrocarbon systems to the present day when their outstanding performance as light stabilisers has been the object of much scientific research. Although some features of their reactivity remain obscure, the authors approach the problem kinetically and indicate the factors limiting their effectiveness.
