Electronic and vibrational dynamic solvent effects on Raman spectra

We report a methodology for the theoretical evaluation of nonequilibrium so lvent effects on Raman intensities within the nonequilibrium Polarizable Co ntinuum Model. Effects due to an incomplete solvent response both to the ex ternal field-induced oscillation in the solute electronic density and to mo lecular vibrations are considered. The extent of such effects on absolute s cattering factors and relative intensities of few simple molecules (HCHO, F CHO, FCFO, ClCHO, CICClO) in various solvents are discussed.
