Abstract : The electronic and vibrational spectra of the series of compounds fluorene, dibenzofuran (diphenylene oxide) and carbazole were examined for the purpose of studying chemical bonding in electronically excited molecules. Assignments of the ground state vibrational frequencies were made to enable study of the change of vibrational frequency on electronic excitation. Spectra of the compounds in the vapor phase were obtained in the ultraviolet region and assignments of vibronic frequencies were made. (Author)
