Abstract:
The rotational spectra of the nascent NO(X2 Πv″=1,2,3) product from the photolysis of nitrosobenzene(C6H5NO)have been recorded by using the single-photon laser-induced fluorescence (LIF) technique. The rotational temperature and the relative ratio of vibrational population of the nascent NO(X2 Π) photofragment were obtained by probing the internal-state distribution of the fragment. The energy disposal in the photodissociation of nitrosobenzene at 266 nm was studied. In contrast to small molecule, the large-size molecule C6H5NO, gives rise to a broad-energy distribution involving all degrees of freedom in photodissociation.

摘要:
利用单光子激光诱导荧光(LIF)技术,测量了亚硝基苯(C6H5NO)初生态光解碎片NO(X 2Π v″=1,2,3)的转动光谱.通过对初生态光解碎片NO(X 2Π )内能态布居的分析,得到了NO(X 2Π )的转动温度和相对振动布居比,研究了亚硝基苯在266 nm激光光解过程中的能量配置情况.与小分子相比,大的亚硝基苯分子,其光解过程中能量分布很宽,涉及到所有自由度.
