Resonance and pre-resonance Raman spectra are presented for the 1:1 and 3:1 solid complexes of perylene with tetracyanoquinodimethane (TCNQ). Selective resonance enhancement was observed for perylene. A study of the frequency dependence of the Raman intensities shows that, although these are weak complexes, complexing has a marked influence on the scattering intensities.
