    High-pressure Raman study of methyl iodide (CH3I and CD3I) up to 12 GPa (1992)

    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.

    High-pressure Raman study of liquid and solid ethanol at pressures up to 17 GPa (1990)

    Notes: High-pressure Raman spectra of liquid and solid ethanol were measured at pressures up to 17 GPa and 300 K in a gasketed diamond anvil cell. The frequencies of in-phase and out-of-phase O—H stretching vibrations which characterize the hydrogen bond along the zig-zag chain decrease with increasing pressure with slopes(dν/dP) of -14.3 and -12.4 cm-1 GPa-1, and they overlap with the CH stretching mode at about 11 and 17 GPa, respectively. No solid-solid phase transition was observed at pressures up to 17 GPa.

    High-pressure Raman study of liquid and crystalline CHF2Cl and CHF3 (1993)

    Notes: High-pressure Raman spectra of liquid and crystalline CHF2Cl and CHF3 were measured up to pressures of 15 and 10 GPa, respectively, at 300 K in a gasketed diamond-anvil cell. The liquid-solid phase transition pressures were determined to be 3.49 GPa for CHF2Cl and 2.46 GPa for CHF3. For both CHF2Cl and CHF3, the wavenumbers of the C—H stretching mode ν1 increased rapidly with increasing pressure, and this behaviour was investigated by the theory of reasonance hybrid of the covalent-bonded and ionic-bonded structures.
