| Popis: | Electronic absorption, fluorescence and fluorescence polarization spectra of 4H-benzo[def] carbazole were experimentally characterized. Two molecular orbital techniques (MIM and PPP) were used to calculate the properties associated with the electronic states. By comparison of theory and experiment a complete assignment of the electronic transitions was possible. The dipole moment of the first excited state was evaluated from the solvent shifts of absorption and fluorescence bands and compared with theoretical expectations. |
