| Outline of Final Research Achievements |
We developed an advanced quantum chemical theory based on density matrix renormalization group (DMRG) for accurately describing complex chemical phenomena associated with reaction pathways mediated through several different electronic states, such as excited states, spin states, oxidation states, etc. In order to properly account for electronic processes involved with multiple electronic states, the multi-state second-order quasi-degenerate perturbation theory was developed and implemented into an efficient computer program. Using the resulting theoretical method, we studied multinuclear transition metal complexes (manganese cluster, diferrate, desaturase) and photofunctioning organic molecule (spiropyran) to elucidate electronic details of the reaction mechanisms and chemical bondings.
