| Outline of Final Research Achievements |
We have studied a new class of chemical dynamics to be found in molecular electronic excited states embedded in densely quasi-degenerate state manifolds, in which a huge fluctuation is induced due to persisting multidimensional nonadiabatic transitions among the states. The relevant phenomena can result in intramolecular energy redistribution, which we call intramolecular nonadiabatic electronic-energy redistribution. Despite the huge fluctuation, strong chemical bonding coexists to assist the molecules to survive. Such complex electronic excited states are found in, for example, boron and carbon clusters. Those excited states have been analyzed with our developed energy natural orbitals (ENO). It turns out that ENO energy spectra are composed of four robust layers of different physical natures. In the layer structure, the physical origin of the robust chemical bonds has been identified. We also have found novel electronic-state quantum chaos behind the fluctuation.
