| 摘 要： | 本文报道在交叉分子束装置中, 研究氧原子和CF2=CFCl, CF2=CFBr,CF2=CH2的反应。在O(^3p)和CF2=CFBr(或CF2=CFBr)反应中, 首次观察到反应生成的CF2(^3B1)的发射光谱, 而在O与CF2=CH2反应中, 用激光诱导荧光方法检测到CFH卡宾, 确定了在此反应中CFH卡宾的生成, 这一结果未见文献报道。并根据这些结果, 分析和讨论了在这些反应中, 生成CF2(^3B1)和CHF卡宾的机理。

| Abstract: | The reactions of oxygen atoms with CF2=CFCl, CF2=CFBr and CF2=CH2 have been investigated by crossing molecular beam apparatus. The paper reported that the emission spectrum of CF2(^3B1) carbene produced by the reaction of O(^3p)+CF2=CFCl(or CF2=CFBr) has been observed and the CFH carbene produced by the reaction of O(^3p)+CF2=CH2 has been identified by laser induced fluorescence spectrum, respectively for the first time. Otherwise, these reactive mechanisms were analyzed and discussed simultaneously in this paper. |
