Abstract

The infrared and Raman spectra of vanadyl(IV) tetraphenylporphyrin were recorded between 1600 and 200 cm^−1^. Assignment of most of the vibrational modes was done by comparison with other related compounds. The VN and VO metal—ligand vibrations could be clearly identified. Pre‐resonance experiments were performed, using different radiation from an argon ion laser, in the energy range between the main electronic transitions of the complex [the Soret band and the (α + β) doublet]. Analysis of the excitation profiles suggests that all the enhanced bands contribute to both the A and B terms of Albrecht's equation.
