Notes:
High-pressure Raman spectra of liquid and crystalline CH3I and CD3I were measured up to 12 GPa at 300 K in a gasketed diamond-anvil cell. The liquid-solid phase transition pressures were determined as 0.9 GPa for CH3I and 0.8 GPa for CD3I. For both CH3I and CD3I, two translational and two librational modes were observed in the pressure-induced solid phase. The frequencies of the librational modes increased rapidly with increasing pressure. The frequency of the intense ν3 mode also increased rapidly with pressure. Splitting of fundamental modes was found in the solid phase, and this behaviour is discussed in terms of crystal field effects.
