Due to this fact spin exchange is now widely used in solving various problems of chemistry, physics, and molecular biology. Spin exchange allows one to study in detail elementary acts of collisions of molecules. By use of spin exchange one can obtain quantitative information on collision rates of molecules in solutions, steric hinderance in collisions, electrostatic interactions in collisions of charged particles, and overlap of electron orbitals in collisions. Par­ ticularly valuable is the possibility of using spin exchange to study col­ lisions in such complex systems as polymer solutions, multicomponent mix­ tures, heterogeneous mixtures, and especially biological systems. This monograph contains a comprehensive description of spin exchange in solutions. It consists of four chapters. The introductory chapter contains a brief summary of the physical principles of spin exchange and outlines the range of its main applications. In this chapter a historic background of research in this field is also given. The second chapter contains a com­ prehensive presentation of the theory of spin exchange including that of its spectroscopic manifestations. The third chapter is devoted to a detailed description of the technique of experimental studies of spin exchange. The last - the fourth - chapter summarizes the results of experimental studies of spin exchange and considers various applications of spin exchange in che­ mistry, molecular physics, and biology."

Spin states in biochemistry and inorganic chemistry: influence on structure and reactivity / Swart, Marcel

Public ISBD Titre : Spin states in biochemistry and inorganic chemistry: influence on structure and reactivity Type de document : texte imprimé Auteurs : Swart, Marcel, Auteur ; Costas, Miquel, Auteur Editeur : Chichester : Wiley Année de publication : 2015 Importance : xiii, 448 p. ISBN/ISSN/EAN : 978-1-118-89831-4 Note générale : It has long been recognized that metal spin states play a central role in the reactivity of important biomolecules, in industrial catalysis and in spin crossover compounds. As the fields of inorganic chemistry and catalysis move towards the use of cheap, non-toxic first row transition metals, it is essential to understand the important role of spin states in influencing molecular structure, bonding and reactivity.

The successes and pitfalls of theoretical methods such as DFT, ligand-field theory and coupled cluster theory are discussed, and these methods are applied in studies throughout the book. Important spectroscopic techniques to determine spin states in transition metal complexes and proteins are explained, and the use of NMR for the analysis of spin densities is described.
