The electronic transitions of [Ru(NH3)(4)bipyridine](2+) (R4AB) in the visible region are solvatochromic due to hydrogen bonding interactions with the solvent. In this work, we employ resonance Raman and absorption spectroscopy to separate the static and dynamic contributions to the solvatochromic shift. Raman excitation profiles for R4AB in methanol (MeOH) and dimethylsulfoxide (DMSO) were obtained at wavelengths within the lowest energy absorption band, which comprises two overlapping metal-to-ligand charge transfer (MLCT) transitions (the red band), and preresonant with a higher energy blue band. The absorption and Raman profiles of R4AB were analyzed using time-dependent theory to determine the 0-0, internal, and solvent reorganization energies, the sum of which is the energy of maximum absorption. It is concluded that the solvatochromic shift in the transition energy of each of the two visible MLCT bands is due mainly to changes in the 0-0 energy, while the internal and solvent reorganization energies are found to be similar in MeOH and DMSO. Preresonance enhancement via the blue band is larger in methanol than in DMSO. The question of the composite nature of the visible absorption band is addressed by modeling the low-temperature absorption spectrum, where two peaks in the red are resolved. The dimensionless displacements derived from the Raman modeling are shown to be consistent with attributing the structure to two overlapping electronic transitions rather than a vibrational progression. Depolarization ratio dispersion was found to be difficult to model, probably due to strong preresonance enhancement which is only accounted for phenomenologically in this work.
