The picosecond time resolved resonance Raman spectra of the MLCT excited state have been observed in room temperature water, in isopropyl alcohol, in 4:1 ethanol/methanol above and below the glass transition temperature, and in anionic SDS micelles. In all cases the excited electron is localized on one bipyridine ligand. The vibrational relaxation-localization process appears to be complete within a few picoseconds. A broadening of MLCT Raman lines at high field intensities is attributed to nonlinear resonance scattering. Localization and subsequent electron hopping are discussed with use of the simple Franck-Condon electron transfer model for weakly coupled, mixed valence compounds.
