A Franck-Condon theoretical model of electronic-vibrational interactions was used to analyze the finely structured fluorescence and absorption vibrational structure of 1,4,5,8-tetrahydroxyanthraquinone and its d/sub 4/ derivative in order to analyze the change in the equilibrium nuclear configuration of polyatomic molecules in excited electronic states. The results of the calculations suggest that an appreciable change occurs in the angles of the molecule in the excited state.
