| 摘 要： | 本文在流动余辉装置上，研究了亚稳态H2(2^3S）原子与N2H4分子碰撞传能，观察到了激发态产物NH（A^3п→X^3∑^ ）、NH（c^1п→a^1△）、NH2（A^~A1→X^2△B1)的发射光谱，由相对光谱强度求得了形成各产物的通道比；分析NH（A^3п,v′＝0）的转动分辨谱的结果表明，v′＝0能级上的转动布居是“双模”分布，激光态产物NH（A）、NH2（A）的形成机理可能是：He(2^3S) NH2H4 N2H4→NH2H4^*→NH(A) NH2(A) H。

The Chemiluminescence of the Products in Energy Transfer Reaction of
Metastable Atom He(23S) with Molecule N2H4 |
| |
| Abstract: | The energy transfer reaction of metastable atom He(23S) with molecule N2H4 was studied using discharge-flowing afterglow technique. The emission spectrum of excited radical NH(A3∏→X3∑+). NH(c1∏→a1△). NH2(A2A1 → X2B1) were observed. The ratios of formation products exit were obtained by relative spectra intensity. The emission rotational spectra of product NH(A3∏,v′= 0) were analysed,the results showed that rotational populations were " two models". The formation mechanism of excited products was: He (23S)+N2H4→N2H4→NH(A)+ NH2(A)+H. |
