EnglishWe report some results on the calculation of vibrational spectra of molecules in condensed phase with accounting simultaneously for anharmonicity and solute-solvent interactions, the latter being described by means of the polarizable continuum model (PCM). Density functional theory force fields are employed as well as a new implementation of the PCM cavity and its derivatives. The results obtained for formaldehyde and simple peptide prototypes show that our approach is able to yield a quantitative agreement with experiments for vacuo-to-solvent harmonic and anharmonic frequency shifts.
