Raman spectra ofZn (SCN) <SUB>2</SUB> · 30DMS0 · 4NaSCN solution (DMSO=dimethylsulfoxide) were measured at high pressures and room temperature. The effect of pressure on the interactions between Zn<SUP>2+</SUP> ions and SCN<SUP>-</SUP> ions and the solution structures were examined. The relative intensity of the symmetric C-N stretching vibration due to SCN<SUP>-</SUP> ions decreases with increasing pressure. Peak frequencies of both symmetric (in-phase) and asymmetric (out-of-phase) C-N stretching vibrations decrease up to 100 MPa as the pressure increases. The self-association of DMSO molecules in this solution increases with increasing pressure. With these results, it is suggested that [Zn (NCS) <SUB>4</SUB>]<SUP>2-</SUP> complexes form the solvent-separated complex pairs at higher pressures.
