Raman and infrared spectra of intact and metal-substituted chlorophyll a were observed in the solid state and in solution.Ni, Cu, Zn, and Ag were used to substitute Mg.Nine series of metal-sensitive bands were found in both the Raman and infrared spectra in the solid state.The frequencies of these metal-sensitive bands are considered to be linear functions of the Ct-N distance (Ct is the center of the chlorin ring and N is the nitrogen atom in the pyrrole ring), by analogy with the relationships established for metalloporphyrins.
