Notizen: High-pressure Raman spectra of liquid and solid thiophene C4H4S have been measured up to 100 kbar at 300 K in a gasketed diamond anvil cell. The pressure dependence of intramolecular and intermolecular vibrational modes revealed a solidification point at 6 kbar and a pressure-induced phase transition at 40 kbar. This solid-solid phase transition was identified as the III→IV phase transition by comparison with the intermolecular Raman spectra of the low-temperature solids at atmospheric pressure. The appearance of a dark-red modification of C4H4S, which is irreversibly formed at pressures above 80 kbar with laser irradiation, is discussed.
