| 摘 要： | 利用高分辨光谱技术他NH2（A~2A1,090)423(F1/F2) 在单次碰撞条件下的精细态色散光光谱，发现NH2（A~2A1)在与团壳层分子碰撞传能过程中，母能级的自旋－转动耦合守恒，从实验上直接证实了在开壳层－ 壳层分子碰撞过程中电子自旋为一旁观者的假设；由于长程作用力造成子能级有保持原来自旋－转动耦合的倾向。

| Abstract: | By using the high resolution dispersion spectra of NH2(~A2A1,090) 423(F1/F2) it is ob-served that the spin-rotational conservation transition is dominant for the parent levels. It con-firms the assumption that the electron is a spectator at single collision between open-shell and close-shell molecules. As to the daughter levels, the tendency for the conservation of the spin-rotation coupling of the parent level is found and may be explained by the long range interaction between those molecules. |
