Abstract

Picosecond resonance Raman has been employed in a two-color pump/probe experiment to re-evaluate the assignments of metal to ligand charge transfer ground and excited state bands in tris-2,2′-bipyridine Ru(II). It is shown that there is no spectral overlap between ground and excited state bands and that all ground state bands originate from pure ground state molecules rather than from molecules containing one excited state ligand and two unexcited ligands as previously suggested. Several excited state bands which were unresolved in previous experiments are clearly observed in the two-color spectrum. These results do not affect the general conclusion that the excited state is representative of an electron localized configuration. © 1988.
