Biography Terenina Alexander
Terenina, Alexander (1896-1967), Russian physical chemist. Born on April 24 (6 May) 1896 in Kaluga. In 1907 enrolled in the local real school. In 1914 he moved to Petrograd, worked in the mental institute. In 1916-1918 studied spectral analysis and photometry in the scientific laboratories of the military departments. At the same time was a volunteer university; in 1918, was enrolled at the Faculty of Physics of the University, which he graduated in 1922. From 1919 he worked at the State Optical Institute: first as a laboratory for the workshops, then an assistant engineer, physicist, head of the laboratory of photochemistry, and from 1945 - Director. Since 1932 he was a professor and chair of Optics University of Leningrad (succeeding DS Rozhdestvensky). Since the founding of the Research Institute for Physical LSU (1933) in charge of its optical division, and then - the Laboratory of Optics of surface phenomena.
In 1924 Terenin set became a classic experience of dissociation of sodium iodide (NaI), located in a gaseous state, the sodium, fluorescent yellow light, and iodine. He followed the behavior of the electron, which connected both ion molecule, and after breaking the link was added to the atom, but in the excited state. This work is to research the mechanism of photochemical reactions. Continuing complicating the objects of research, Terenin and his students have moved from the gas molecules to organic molecules, found the complex processes of vibrational energy redistribution.
Of great importance was the work Terenina for the Study of photochemical reactions in the surface layer, where the adsorption of molecules, in particular to establish the mechanism of action of catalysts (1934). In 1939 Terenin began studying the photovoltaic phenomena in organic and inorganic compounds. In 1943, he put forward a hypothesis about the nature of the triplet metastable states responsible for phosphorescence of organic compounds. In 1945 applied spectral methods to the study of photochemical reactions involving chlorophyll and its analogs.
For scientific merits Terenin was awarded the Gold Medal. Vavilov and other orders and medals, awarded the State Prize of the USSR.
Terenin died in Moscow on January 18, 1967.
