Abstract
We report and discuss Raman spectra of porphin. These were obtained by resonance effect, irradiating in the electronic band IV. Unexpected variations of vibrational band intensities and depolarization ratios were recorded on changing the excitation wavelength. Some implications on the symmetry types of the vibrations are discussed. Results are compared with current data from quasi-linear electronic spectra.
