Assignment of charge transfer bands for a bridged binuclear metal complex by resonance Raman excitation profiles

Resonance Raman spectra obtained using laser excitation wavelengths varled to match each of two visible charge transfer absorption bands of a dimeric metal complex with two different diimine ligands vary significantly. The identification of characteristic ligand vibrations leads to the assignment of the two metal‐to‐ligand charge transfer transitions with respect to the ligand which accepts the charge in the excited state. The resonance Raman spectra provide information relating to the complex structures in solution.
