利用分子束装置研究了F与CH~3F反应可见光范围(450-900nm)的化学发光.观察到HCF(A~1A"-X2A')的七个振动带和HF^+电子基态振动广频跃迁的四个振动带和它们的强度随反应物流量的变化.求得HF分子的V'=4,5,6能级相对振动布居和V'=3的转动温度.分析表明两种光谱都是第二步反应(F+CH~2F)引起的,这步反应造成了HF高振动能级的统计性粒子分布和转动能级的玻尔兹曼分布.

By using mol. beam apparatus the visible (450-900 nm) chemiluminescence of the reaction of F with CH3F was investigated. Seven vibronic bands of HCF(?A''-X1A') and 4 vibrational bands of HF ground state overtone transitions were obtained. The relative vibrational state distributions of HF (V' = 4, 5, 6) states and the rotational temperature of HF (V' = 3) state were obtained. The analyses show that the 2 kinds of spectra were caused by the secondary reaction F with CH2F. This reaction causes the statistical distribution of HF high vibrational levels and the Boltzmann distribution of the HF rotational levels.
