摘要
利用激光诱导荧光技术 ,实验测定了NO2 分子 5 13～ 5 2 0nm范围内 ～A2 B2 电子激发态 6个不同振转能级激光诱导荧光衰减寿命 ,研究了激发态荧光寿命与气压和激发波长的关系 ,得到了无碰撞衰减寿命和碰撞猝灭系数 ,并对其反常长寿命进行了讨论。
In this paper, the radiative fluorescence lifetimes of electronic excited states of NO 2 were measured at six different excitation wavelength in the region of 513～520 nm. The dependence of the fluorescence lifetime on gas pressure and excited wavelength were also studied. By using the Stern-Volmer mechanism, the collision-free radiative lifetimes and collisional quenching rate constants were obtaind. The apparently anomalously long lifetime of NO 2 was discussed with the perturbation theory.
