The pressure dependence of the main spectral lines in Raman spectra of antracene and of 1 M water solutions of NaClO4 and Na2WO4 was measured by optic cell with sapphire windows at pressures up to 140 MPa. The obtained values of spectral shifts (from 0.6 to 1.1 cm-1 per 100 MPa) correspond to those described in literature for 1 M water solution of sodium sulfate.
