| 英文摘要 | The ultrafast dynamics through conical intersections in 2,6-dimethylpyridine has been studied by femtosecond time-resolved photoelectron imaging coupled with time-resolved mass spectroscopy. Upon absorption of 266 nm pump laser, 2,6-dimethylpyridine is excited to the S_2 state with a ππ~* character from So state. The time evolution of the parent ion signals consists of two exponential decays. One is a fast component on a timescale of 635 fs and the other is a slow component with a timescale of 4.37 ps. Time-dependent photoelectron angular distributions and energy-resolved photoelectron spectroscopy are extracted from time-resolved photoelectron imaging and provide the evolutive information of S_2 state. In brief, the ultrafast component is a population transfer from S_2 to S_1 through the S_2/S_1 conical intersections, the slow component is attributed to simultaneous IC from the S_2 state and the higher vibrational levels of S_1 state to So state, which involves the coupling of S_2/S_0 and S_1/S_0 conical intersections. Additionally, the observed ultrafast S_2→S_1 transition occurs only with an 18% branching ratio. |
