英文摘要	The ultrafast dynamics of benzene on the S-2 state have been investigated by femtosecond time-resolved mass spectroscopy coupled with photoelectron imaging. The benzene molecule was excited to the S-2 state by two 400 nm photons, and subsequently probed by one 267 nm photon. The time-dependent ion yield of the parent ion consists of two components with different lifetimes. The first component at (90 +/- 1) fs is because of internal conversion from the S-2 state to the S-1/S-0 state. The second one, i.e., (5.0 +/- 0.2) ps, is due to decay of the S-1 state. The observed lifetime of the second component is shorter than previous results, indicating the existence of an additional decay process. With photoelectron spectra extracted from the time-resolved photoelectron imaging, this newly found deactivated process is assigned to intersystem crossing from the vibrational excited S-1 state to the hot triplet state T-3.
