135 GROSS 



In 1940 Gross proposed a spectroscopic method for determin- 

 ing orientational relaxation times of molecules from aniso- 

 tropic scattering. In 1951, he discovered an optic spectrum of 

 excitons which transmit energy of excited states in crystals. 

 In 1954-55, he discovered in excitons the Zeeman and Stark ef- 

 fect and the disassociation of excitons under the influence of an 

 external electrical field. In 1956, he discovered the radiation 

 spectrum of excitons, their large diamagnetism, and their role 

 in inner photo -effect.
