✦ Synopsis

The effects of pressure on the frequencies and band structures of the Raman active inter-and intramolecular vibrations of 1,2,4,5-tetrafluorobenzene crystal were studied under hydrostatic pressures from 1 atm to 4 GPa at 300 K in a gasketed diamond anvil cell. Changes of the Raman frequencies and band behaviors of both the inter-and intramolecular vibrations due to the application of pressure indicate that the phase transitions take place under about 0.3 and 3 GPa.
