| 英文摘要 | the dynamics of the first excited singlet electronic state (s-1) of o-dichlorobenzene was investigated in real time by the femtosecond pump-probe method combined with time-of-flight mass spectroscopy and the photoelectron velocity mapping technique. the lifetime of the s-1 vibrational ground state was determined experimentally to be (651 +/- 10) ps, corresponding to the intersystem crossing process from the s-1 state to the triplet state. two decay channels were found in the s-1 vibrationally excited mode 9a(2)18a(2). the fast process (lifetime constant (458 +/- 12) fs) is because of the internal conversion from the s-1 vibrationally excited mode to the highly vibrationally excited ground state (s-0). the slow process (lifetime constant (90 +/- 10) ps) is attributed to the intersystem crossing process from the s-1 state to the triplet state (t-1). photoelectrons with long lifetime characteristics in the spectrum might be connected with the intersystem crossing process. enhanced spin-orbital coupling in the s-1 highly vibrationally excited state accelerates the intersystem crossing process. |
