The resonance Raman spectra of tetracyanoquinodimethane anion (TCNQ^{-}) and naphthalene cation (C_{10}H^{+8}) are analyzed in terms of theoretical model based on the Franck-Condon effects. The model includes also the effect of rotation of totally symmetric normal coordinates upon electronic excitation to the resonant state (Dushinsky effects). It is shown that such a simple model accounts correctly for the available resonance Raman spectra for TCNQ^{-} and C_{10}H^{+8} radicals. The possible model refinements such as vibronic coupling effects are also briefly discussed.
