The Bruker Lecturer for 2006

Professor Yuri D Tsvetkov

For his contribution to the development of pulsed EPR techniques, especially for distance determinations via pulsed electron double resonance, and its applications in free radicals research.

Professor Yuri. D Tsvetkov, is now Scientific Advisor of the Russian Academy of Sciences. Between 1993-2003 he was Director of the Institute of Chemical Kinetics and Combustion, Novosibirsk and Head of the Laboratory of Chemistry and Physics of Free Radicals. Since 1994 he is a Member of the Russian Academy of Sciences.

After graduation from the Moscow Physico-Technical Institute in 1957, he worked at the Institute of Chemical Physics of the Academy of Sciences before moving to the Institute of Chemical Kinetics and Combustion in Novosibirsk, where he gained his Ph.D (1961) and Dr.Sci. (1971).

From 1983-1992 he was General Scientific Secretary of the Siberian Branch of Russian Academy of Sciences. His research has concentrated on applications of EPR techniques to the structure and properties of free radicals in irradiated polymers, acids, amino acids, and peptides including the kinetics and mechanism of oxidation in irradiated polytetrafluoroethylene.

Since 1966 Professor Tsvetkov has developed and applied electron spin echo (ESE) spectroscopy to study magnetic relaxation in spin systems; the spatial distribution of atoms, ions, and radicals in irradiated solids; the super slow motions of organic radicals in amorphous matrices; the kinetics and the mechanisms of various fast light-induced chemical reactions; the structure of paramagnetic centers and their environments; and dipolar spectroscopy using pulsed electron-electron double resonance.

The author of several books and reviews and more than 290 research papers, he is a member of the editorial board of the Journal of Structure Chemistry, High Energy Chemistry, Applied Magnetic Resonance, and member of IES, ISMAR, AMPERE societies.

In 1988 he won the USSR State Scientific Prize and in 1999 the IES Silver Medal for Chemistry. He is currently the President of the International EPR Society.
