Physical labels such as stable nitroxide radicals, luminescent and photochromic chromophores, so-called Mössbauer atoms and electron-dense assemblies of heavy atoms have proved to be effective tools in solving many problems at the molecular level in biological systems. These physical labels are used as 'molecular rulers' to measure the distances between chosen groups and to measure the size, form and microrelief of objects. By providing information about these factors, the label provides information that can help the scientist to understand the structure of membranes, nucleic acids, enzymes and proteins and how they function. This 1993 volume covers all aspects of this field: the theoretical bases, the experimental techniques, and it also shows how to interpret the resulting data. It also critically discusses some recent results obtained with these techniques and gives an analysis of likely developments in the future. - Inbunden, Engelska, 1993

Covering all aspects of this field, this volume also critically discusses recent results obtained with the use of nitroxides, while providing an analysis of future developments. Written by a group of scientists with long-term experience in investigating the chemistry, physicochemistry, biochemistry and biophysics of nitroxides, the book is not intended as an exhaustive survey of each topic, but rather a discussion of their theoretical and experimental background, as well as recent advances. The first four chapters expound the general theoretical and experimental background and the advantages of modern ESR technique. Chapter 5 focuses on fundamentals and recent results in the preparation and basic chemical properties, while the next two chapters briefly outline principles and current results in nitroxides as spin probes, and as redox probes and spin traps. These chapters form the basis for the subsequent more detailed studies of nitroxides in physicochemistry, while the final chapters concentrate on the advantages of magnetic materials on the basis of nitroxides. Finally, the concluding chapter considers the rapidly developing field of biomedical, therapeutic and clinical applications. With more than 1,100 references to essential literature, this volume provides fundamental knowledge of instrumentation, data interpretation, capacity and recent advantages of nitroxide applications, allowing readers to understand how nitroxides can help them in solving their own problems. - E-bokEngelska, 2012

"Chemical physics is a science of the physical foundations of chemical transformations" (N. N. Semenov). The main objective of chemical physics is to disclose the detailed mechanism of chemical reactions and to learn to control these processes. The physico-chemical approach hinges upon the extensive application of methods of molecular physics and chemical kinetics. Based originally on simple gas-phase processes, chemical physics gradually extended its sphere of interest to liquid-phase reactions and to processes taking place in solids, including polymers. At present, we witness the fact that the ideas and methods of this science penetrate deeper and deeper into modern molecular biology, including enzyme catalysis. This monograph treats, from the standpoint of modern chemical physics, the principal general and individual features of the structure and mechanism of action of various classes of oxidation-reduction (redox) metalloenzymes. There are several reasons for which this branch of science attracts the attention of specialists in various fields - from biologists and those working in medicine to chemists and theoretical physicists. First of all, is the enormous biological and biochemical importance of processes catalyzed by metalloenzymes. These include biological ox idation with oxygen, oxidative and photo-phosphorylation, atmospheric nitrogen fixation, assimilation of nitrates and sulphites, phototransport of electrons, hydrogen evolution and hydrogenation and photo-oxida tion of water, which is far from a complete list of such processes.
