Raman investigation of Peierls-Hubbard (TTF^{+})_{2} dimers in (TTF)_{2}Mo_{6}O_{19} and (TTF)_{2}W_{6}O_{19} salts have been performed. It was found that the resonance enhancement of Raman intensity of intramolecular vibration modes exists only when the frequency of excitation light fits to the localised electron transition, however, the resonance enhancement of intermolecular modes occurs when the frequency of excitation light corresponds to the charge transfer transition.
