| 英文摘要 | the predissociation decay behavior of molecule carbonyl sulfide (ocs) has been investigated by resonance-enhanced multiphoton ionization spectroscopy using the pump-probe technique of dichroic femtosecond lasers in real time. the lifetime of excited ocs around 74 720 cm(-1) by two-photon absorption of 268 nm, corresponding to upsilon(1)=1 of the rydberg state [(2)pi(1/2)]4ppi((1)sigma(+)), is directly determined to be tau(d)=1071+/-11 fs. this picosecond decay process indicates that the excited state is predissociative. the temporal information of dissociation enriches the knowledge of the potential-energy surface of the associative excited state. |
