Resonance Raman spectra of model complexes for reduced cytochrome P450 and its carbonyl and dioxygen adducts have been obtained with Soret excitation. The frequencies of the mainporphyrin vibrations do not stress any specific influence of the thiolate ligand. Isotopic substitution permits assignment of the 479-cm" 1 Raman lineof Fe (TpivPP)(C6HF4S")(CO) to the Fe-CO stretching vibration and the 1140-cm" 1 Raman lineof Fe (TpivPP)(C6HF4S")(02) to the 0-0 stretching vibration. These frequencies are discussed with special reference to the CO and 02 adducts of Fe (TpivPP)(7V-MeIm), a model complex for Mb and Hb. The concomitant weakening of the Fe-CO and COvibrational frequencies of Fe-(TpivPP)(C6HF4S")(CO) is explained by the-donor character of the thiolate ligand.
