High-pressure Raman spectra of frustrated antiferromagnet CS 2 CUCl 4 is investigated in a diamond anvil cell. Four characteristic modes of CS 2 CUCl 4 are observed at ambient conditions. As the pressure increases, the sample undergoes a structure phase transition at 5 GPa. After decompressing, the low-pressure Raman spectra are recovered, which indicates a reversible phase transition. We discussed the results in terms of the change of structure with pressure.
