利用高分辨光谱技术观察了NH2 ( A2 A1,0 90 ) 42 3(F1/F2 )在单次碰撞条件下的精细态色散荧光光谱 ,发现NH2 ( A2 A1)在与闭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 -闭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具有保持原来自旋 -转动耦合的倾向。
The fine-state fluorescence spectra of NH2 (A2 A1,0 90) 42 3 (F1 / F2) under single-impact conditions were observed by high-resolution spectroscopy. It was found that NH2 (A2 A1) In the process, the spin-rotation coupling conservation of the parent level directly confirms the hypothesis that the electron spin is a bystander during the shell-shell collision; the sub-level due to the long-range force Has the tendency of keeping the original spin-rotation coupling.
