本文利用交叉分子束技术和激光诱导萤光方法, 研究了F+i-C3H7I→IF+i-C3H7反应的动力学过程. 获得了产物IF相对初生振动分布和相对细致反应速率常数. 初生态布居接近于模型III下的统计理论斯待值, 这不仅表明反应经过长寿命“配合物", 而且也说明自由基i-C3H7的内态是激发的. 另外, 确定了反应的产物IF内部能量分配和总反应截面σ, σ=(3.6±0.5)×10^-^1^6cm^2.

The dynamics of the title reaction was investigated using the crossed mol. beam technique and the laser-induced fluorescence method. The relative nascent vibrational state distributions of the product IF and the relative detailed reaction rate constants have been obtained. The state populations are close to the statistical expectations, indicating that the reaction proceeds through a long-lived complex and the iso-Pr radical is excited. The internal energy disposal of IF and the total reaction cross section were determine
