Popis:	To evaluate the effects of sequential pyrrole ring reduction, we have examined the vibrational spectra of tetracoordinate Zn(II) complexes of meso-tetraphenylporphyrin [Zn(TPP)], meso-tetraphenylchlorin [Zn(TPC)], and meso-tetraphenylisobacteriochlorin [Zn(TPiBC)]. The phenyl substituents of these macrocycles fall into distinct symmetry classes; for Zn(TPP), all four phenyl groups are equivalent; for Zn(TPC), the phenyl groups are of two different types; and for Zn(TPiBC), there are three types of phenyl substituent
