| Outline of Final Research Achievements |
A fundamental electronic structure theory has been developed for a proper and accurate description of the electronic excited states of large molecular systems based on the wavefunction theory. Also, an analyzing method has been proposed for complicated electronic-excited states in large molecular systems. The theory can be applied for studying excitations, photo-absorption and fluorescence, fluorescence quenching, photoionization, charge-separation, radical dissociations, excited-state proton-transfer, and so on. The solvent effects and intermolecular interactions can be incorporated into the theory. The theory and computational method have been applied for the analyses of state-of-the-art experimental studies on designing new functional dyes. We have performed the comparison between our wavefunction theory and the conventional density functional theory to investigate the validity and limitation of the density functional theory computations for chemical processes in excited states.
