This article summarizes two major areas of research, electron transfer and organometallic photochemistry, addressed during the last dozen or so years. The article emphasizes aspects of the mechanisms of photochemical reactions of transition metal complexes in these two areas. Excited state electron transfer and photoreactions of organometallic complexes have been, and will be, major areas of research opportunity. Practical applications may come in the fields of energy conversion and catalysis. (Author).

Electron Transfer Reactions deals with the mechanisms of electron transfer reactions between metal ions in solution, as well as the electron exchange between atoms or molecules in either the gaseous or solid state. The book is divided into three parts. Part 1 covers the electron transfer between atoms and molecules in the gas state. Part 2 tackles the reaction paths of oxidation states and binuclear intermediates, as well as the mechanisms of electron transfer. Part 3 discusses the theories and models of the electron transfer process; theories and experiments involving bridged electron transfer; optical electron transfer; and electron transfer in the solid state. The text is recommended for chemists who would like to know more about the principles and mechanisms behind electron transfer reactions.

Conventional and fast-kinetics techniques of photochemistry, photophysics, radiation chemistry, and electrochemistry were used to study the intermediates involved in transition metal excited-state electron-transfer reactions. These intermediates were excited state of Ru(II) and Cr(III) photosensitizers, their reduced forms, and species formed in reactions of redox quenchers and electron-transfer agents. Of particular concern was the back electron-transfer reaction between the geminate pair formed in the redox quenching of the photosensitizers, and the dependence of its rate on solution medium and temperature in competition with transformation and cage escape processes.
