Pressure dependence of the Raman spectra of aqueous solutions and anthracene

Abstract

The shifts of the main bands in the Raman spectra during isothermal pressurization up to 140 MPa for anthracene and 1 M solutions of NaClO4 and Na2WO4 are measured using an optical cell with sapphire windows. The resulting shifts in the maxima of the spectral bands (from 0.6 to 1.1 cm−1 per 100 MPa) are close to the published value for a 1 M Na2SO4 aqueous solution.
