Notes:
Infrared and resonance Raman spectra of 1-hydroxy-9, 10-anthraquinone, its deuteriated and deprotonated forms and its metal chelates with CuII, NiII and CoII ions are presented. Vibrational assignments of the carbonyl, hydroxyl and the chelating unit of this chromophore are emphasized. It is found that the different metal ions force delocalization of the electrons on the chelate rings to different extents. The intensities of the Raman bands under resonance conditions suggest that the electronic band in the visible region is mainly of a charge-transfer type from the metal to the ligand.
