The dynamical process of optical-excited C60 is studied by using the tight-binding model of electron-lattice coupling and solving the real-time Newton dynamical equation. The dynamical evolutions of energy, bond structure and electron states are obtained. The theory shows that the moleule of optical excited C60 turns into a ring-bipolaron-exciton which is consistent with the self-trapped polaron exciton observed in the luminescence experiment of neutral C60.
