采用准经典轨线方法,基于半经验的London-Eyring-Polanyi-Sato势能面,研究了碰撞能对碰撞反应Sr+CH3I→SrI+CH3的立体动力学性质的影响.结果表明,反应物的初始碰撞能对产物转动角动量矢量的取向和定向程度都有重大影响.
Based on the semi-empirical potential field of London-Eyring-Polanyi-Sato, the quasiclassical trajectory method was used to study the effect of collision energy on the stereodynamic properties of collision reaction Sr + CH3I → SrI + CH3. The results show that the initial Collisions can have a significant effect on the orientation and orientation of the product’s angular momentum vector.
