✦ Synopsis

A direct method for evaluation of resonance Raman spectra of cofljugated molecules is applied to the study of the anomalous polarization effect in metalIoporphyrins. The method provides a simpfe explanation for the inverse polarization effect. The quantitative nature of the method allows one to study the phenomenon of anomalous polarization. Calculations of the resonance Raman polarization for AQ vibrations of 1,3,5,7-tetramethyt metalloporphyrin give good agreement with the observed depolarization ratro and its dependence on the excitation energy.

## Abstract Anomalous polarization (ρ = 3/4 ˜∞) has been observed in the resonance Raman spectra of some acetylenecumulene dehydro annulenes of a __D__~2__h__~ rectangular configuration. Because of no orbital degeneracy, the observed anomaly may certainly be explained by the vibronic coupling of th

Novel features in the resonance Raman spectra of metalloporphyrins are predicted to ensue via the recently revealed crossquadralic nuclear potential terms involving modes of different symmetry\_ Such terms were shown to prevail in the doubly degenerate excited electronic states corresponding to the
