运用准经典轨线方法, 基于RODRIGO势能面, 对碰撞能为192.97 kJ/mol时, O+DH反应的立体动力学性质进行了理论研究, 对k-j , k-k 两矢量相关和k-k -j 三矢量相关的分布函数、反应几率、反应截面, 以及产物转动取向参数进行了详细的讨论. 结果表明, 反应物的振动量子数对O+DH (v=0, 1, 2, 3, j=0)→OD+H反应产生了较大的影响.

The dynamic stereochemistry of the O+DH (v=0, 1, 2, 3, j=0)→OD+H reactions were studied using the quasi-classical trajectory (QCT) method on RODRIGO surface. Results indicate that the reagent s vibrational excitation has a considerable influence on the distribution of the k-j , k-k correlation and the k-k -j correlation. In addition, reaction probability and reaction cross section were found to be sensitive to the vibrational quantum number.

Key words: quasi-classical trajectory method, vector correlation, vibrational quantum number, reaction probability, reaction cross section
