Resonance Raman spectra of ( o ‐benzoquinonediimine)ruthenium(II) complexes measured with visible excitation wavelengths show distinct resonance enhancements and intense overtone and combination bands. Assignments of the most prominent fundamental bands are made on the basis of comparisons with theoretical spectra obtained from DFT calculations. Excited state distortions are determined from the resonance Raman intensities and lead to calculated luminescence and absorption spectra in good agreement with experiment.
