He was appointed, in 1949, Chief of the Laboratory of Bio- 

 chemistry of the Institute of Physical Chemistry of the U.S.S.R. 

 Academy of Sciences, and in 1953, Director of this Institute. In 

 1941 he became a member of the Communist Party of the Soviet 

 Union. He was a Corresponding Member of the U.S.S.R. Acade- 

 my of Sciences from 1946 until 1958 when he was elected an 

 Academician. 



Spitsyn's main investigations are in the chemistry of rare 

 elements and in radiochemistry. He showed the reversibility 

 of reactions of chlorination of oxides at high temperature and 

 determined the cause of "sublimation" of some oxides in the 

 atmosphere of chlorine or hydrogen chloride. He investigated 

 thermal stability of alkaline salts of some oxyacids such as 

 tungstates and sulfate, and their volatility in various gaslike 

 media. He investigated the chemistry of heteropoly compounds, 

 and utilized "tagged atoms" in this investigation. 



In March 1958, Spitsyn visited the United States to attend the 

 International Atomic Exposition in Chicago, Illinois.
