用速度图离子成像法研究了N2O在203-205 nm波长范围内的光解动力学。使用标准投影成像和亚像素质心计算获得了0.8%的速度分辨率。用超音速分子束和脉冲束研究了N2O在基电子态的受激弯曲能级的离解。在203-205 nm波长范围内，第一激发弯曲能级的光吸收跃迁几率比基态振动能级的光吸收跃迁几率大7倍。
The photodissociation dynamics of N2O in the wavelength region of 203-205 nm was studied by velocity map ion imaging. A speed resolution of 0.8% was obtained using standard projection imaging and subpixel centroiding calculations. To investigate N2O dissociation starting from the excited bending levels in the ground electronic state, a supersonic molecular beam and an effusive beam were used. The photoabsorption transition probability from the first excited bending level in the wavelength region of 203-205 nm was estimated to be seven times greater than that from the ground vibrational level.
