用266 nm激光解离亚硝基苯（C6H5NO) 产生光解碎片NO，并利用单光子激光诱导荧光(LIF)技术（X2Πν″=0→A2Σ+ν′=0）测得初生态光解产物NO的振转光谱。根据计算所得的模拟光谱对光解碎片NO（X，ν″＝0)的转动量子数J″进行了归属，得到量子数最大到J″＝50.5的各转动能级的相对布居，这表明光解碎片NO具有较高的转动激发。提出了C6H5NO在266 nm下可能的光解机理。

The photodissociation of nitrosobenzene (C6H5NO) at 266nm has been studied by monitoring the nascent NO product using a one-photon laser-induced fluorescence (LIF) technique.The NO （X 2Π ν″=0→ A 2Σ+ ν′=0） ro-vibrational spectrum was obtained. The J" quantum numbers of NO (X, ν″=0) populated in the dissociation process have been assigned by comparing the experimental spectrum with the simulated spectrum. The rotational distributions with quantum numbers up to J″=50.5 were obtained. This means that the NO (X) fragments produced in the dissociation process are of highly rotational excitation. The probable photolysis mechanism is proposed for the photodissociation of C6H5NO at 266nm.
