| 英文摘要 | measurements of the nascent oh product from photodissociation of gaseous nitromethane and nitroethane at 266 nm were performed using the single-photon laser induced fluorescence technique. the oh fragment is found to be vibrationally cold for both systems. the rotational state distribution of nitromethane are boltzmann, with rotational temperature of t-rot=2045 +/- 150 and 1923 +/- 150 k for both (2)pi(3/2) and (2)pi(1/2) states, respectively. for nitroethane, the rotational state distribution shows none boltzmann and cannot be well characterized by a rotational temperature, which indicates the different mechanisms in producing oh radicals from photodissociation of nitromethane and nitroethane. the rotational energy is calculated as 14.36 +/- 0.8 and 4.98 +/- 0.8 kj/mol for nitromethane and nitroethane, respectively. a preferential population of the low spin-orbit component ((2)pi(3/2)) is observed for both nitromethane and nitroethane. the dominant population of pi(+) state in two lambda-doublet states is also observed for both nitromethane and nitroethane, which indicates that the unpaired pi lobe of the oh fragment is parallel to the plane of rotation. |
