The relative intensities of the resonance‐enhanced Raman bands and the solvent effect on these intensities were quantitatively studied for 1,1,4,4‐tetrachloro‐1,3‐butadiene. The results were interpreted on the basis of the normal coordinate treatment in combination with Albrecht's theory of Raman intensities. The vibrational structure of the electronic absorption band was interpreted simultaneously. Information on the molecular structure and normal modes of vibrations in the electronic excited state was obtained. The importance of the normal coordinate treatment in the analysis of the resonance Raman spectra is emphasized.
