SYRKIN, YAKOV KOVOVICH (Physical Chemist) 



Ya. K. Syrkin was born December 5, 1894. In 1919 he gradu- 

 ated from the Ivanovo -Voznesensk Polytechnical Institute, 

 where he taught as a professor beginning in 1925. Since 1931, 

 Syrkin has been professor at the Institute of Fine Chemical 

 Technology. While at Karpov Physico-Chemical Institute, he 

 organized a department on molecular structure. From 1931 to 

 1952, he was scientific chairman of this department. In 1943, 

 he was elected to the U.S.S.R. Academy of Sciences as a Corre- 

 sponding Member. He was awarded a Stalin Prize in 1943. 



The works of Syrkin are concerned with chemical thermo- 

 dynamics, kinetics of reactions in solutions, the mechanism of 

 Menshutkin reactions in solutions and in a gas phase, and in 

 particular, the study of molecular structure and chemical 

 bonds. He applied dipole moments in investigating molecular 

 structure and measured dipole moments for 500 substances. 

 He investigated mechanisms of chemical reactions with the aid 

 of labeled atoms, and intermolecular interaction by dielectric 

 polarization.
