The infrared multiphoton dissociation of CF3CDBrCl in the presence of equimolar CF3CHBrCl was investigated with attention to the isotopic selectivity of the reaction. Large selectivity was found at pressures lower than 3 Torr [1 Torr =(101 325/760) Pa]. Several products were obtained, and the molar fraction of deuterium-containing species (deuterium fraction) of each product was measured. The products were classified into two groups with respect to the pressure and fluence dependences of the deuterium fraction. A reaction scheme, consistent with the experimental results, is proposed.
研究了等摩尔 CF3CHBrCl 存在下 CF3CDBrCl 的红外多光子解离,并关注了反应的同位素选择性。在压力低于 3 托[1 托 =(101 325/760) 帕]时,发现了较大的选择性。得到了几种产物,并测量了每种产物中含氘物种的摩尔分数(氘分数)。根据氘分数的压力和通量相关性,将产物分为两组。提出了与实验结果一致的反应方案。
