The resonance Raman (RR) and time‐resolved resonance Raman (TR 3 ) spectra of the complexes of ruthenium(II) with the ligands 2,2′‐bipyridine (bpy) and 4,4′,5,5′‐tetramethyl‐2,2′‐bipyridine (tmb) are reported. The RR spectra of the ground‐state species show no anomalous behaivor and are consistent with vibrationally isolated chelate ligands. The TR 3 spectra provide definitive evidence that the 3 MLCT excited‐state electron density is localized on the bpy ligand in the three complexes containing this ligand.
