Raman spectra of pressure-induced crystalline CHzBrz have been measured at room temperature for pressures up to 240 kbar in a gasketed diamond anvil cell. The pressure dependence of the internal and lattice modes are reported and discussed. A phase transition appears between 170 and 240 kbar. This h
## Abstract The Raman spectra of hexamethyl benzene and HMBβ__d__~18~ have been recorded as a function of temperature between 4 K and 400 K and as a function of pressure up to 8kbar. In the lowβfrequency region, librational and torsional modes have been distinguished. The spectra indicate a phase t
