Abstract
Resonance Raman spectra of dilute aqueous solutions of Cu-tetrapyridinoporphyrazine have been obtained using a tunable dye and Ar+ lasers. Six bands in the spectra have anomalous depolarization ratios. This is the first observation of anomalous polarization in a molecule of C4h point group symmetry. Intensities and depolarization ratio, ρ1, of the observed bands are measured as a function of the wavelength of the exciting radiation. Bands are assigned to different symmetry species on the basis of the dispersion of their ρl values.Keywords
