Temperature dependence and time evolution of the low frequency Raman spectrum of 4, 4′ -dibromobenzophenone

Temperature dependence of the low frequency Raman spectrum of 4, 4′ -dibromobenzophenone (DBrBP) crystal has been studied in the temperature interval from 340 K down to 10 K. At constant temperature of 10 K the laser power has been gradually increased from 3 mW to 200 mW. Time dependence of the spectra was also examined at the temperature of 10 K and laser power of 30 W.
