| 英文摘要 | dynamics of excited m-dichlorobenzene is investigated in real time by femtosecond pump-probe method, combined with time-of-flight mass spectrometric detection in a supersonic molecular beam. the yields of the parent ion and daughter ion c6h4ci+ are examined as a function of the delay between the 270 and 810 nm femtosecond laser pulses, respectively. the lifetime of the first singlet excited state s-1 of m-dichlorobenzene is measured. the origin of this daughter ion c6h4ci+ is discussed. the ladder mechanism is proposed to form the fragment ion. in addition, our experimental results exhibit a rapid damped sinusoidal oscillation over intermediate time delays, which is due to quantum beat effects. |
