Spectroscopic and electrochemical studies of transition metal tetrasulfonated phthalocyanines: 2—resonant raman spectra of aqueous solutions of cobalt and iron tetrasulfonated phthalocyanines

Raman spectra of the polarized and depolarized light scattered from cobalt and iron tetrasulfonated phthalocyanines in aqueous media at various pH values are discussed and correlated with previously obtained data. The Raman vibrational modes from pyrrole and benzene were used for a tentative band assignment in the frequency range from 200 to 1700 cm −1 .
