Abstract

The interpretation ofthe resonance Raman (RR) spectra ofhemoproteins is based on the normal mode calculations for model compounds - porphyrins and metalloporphyrins. In our works'3 it was shown that the atoms of side substituents participate in vibrations which are active in the RR spectra of porphyrins and hemoproteins. In this paper the interpretation of vibrational coordinates of the porphyrin macrocycle with those of substituents is considered; henceforth this interaction will be called vibrational mixing. The vibrational mixing, firstly, leads to changes in the frequencies and forms many vibrations of the macrocycle and substituents. Secondly, in our opinion, it causes the activation of the modes, in which the main role is played by the substituent, in the RR and vibronic spectra.
