摘要：
Due to the electron-lattice interaction, photoexcitation in Cco induces bond distortion, which forms a sell-trapping exciton and reduces the symmetry of C-60 from I-h to D-5d. The dynamical process of forming the self-trapping exciton is simulated by demonstrating the evolution of both bond distortion and electronic states. It is found that the relaxation time for the exciton trapping time is about 90 fs, which is four times faster than that of charge transfer in C-60.
