AB Selection rules for resonance Raman spectra are given for several porphins of D4h point group symmetry. A normal coordinate treatment is presented, based on a potential function for which stretching and bending force constants are related to bond lengths, and to the product of the bond lengths of the bonds defining the bending angle, respectively. The results can be correlated with the persistent frequencies observed in the resonance Raman spectra of haem proteins where the haem is an iron octasubstituted porphin.
