摘要
运用单光子激光诱导荧光方法 ,研究了NO2 分子在第二吸收带的光解反应动力学 .首次报道了NO2(B2 B2 态 )光解初生态产物NO自由基的v″ =1,2的转动分布 .发现了NO自由基v″ =1的明显双模式分布 .
Photodissociation of NO2 in its second absorption band ( B2B2 state) has been studied by monitoring the nascent NO X(2)Pi product using the single-photon laser-induced fluorescence (LIF) technique. The rotational distributions of the nascent NO photofragment after photodissociation of NO2 at (BB2)-B-2 state have been firstly reported. In nu' = 1, the rotational distributions are bimodal. We proposed that there are two dissociation mechanisms that govern the product internal distributions and the photodissociation mechanism.
