| 英文摘要 | photolysis of gaseous o-nitrobenzalclehyde (o-nba) with selected different excitation wavelengths (355-400 nm) is investigated, and the nascent oh radical is detected by the single-photon laser-induced fluorescence (lif) technique. the relative quantum yield and rotational excitation of 011 formation are found to be dependent on the excitation energy. the distributions of rotational, spin-orbit, and lambda-doublet states are obtained at 355-400 nm by analyzing the experimental data. the oh radicals are found to be vibrationally cold at all photolysis wavelengths. the spin-orbit and lambda-doublet states have nonstatistical distributions. to understand the dissociative process involved in the oh-generating channel, dft calculations are performed. based on both experimental and theoretical results, possible photolysis channels of o-nba leading to the ch fragment are proposed and discussed. |
