分子长程作用导致的电子态转移半径典量子理论

SEMICLASSICAL QUANTUM THEORY OF LONGRANGE\= INTERACTIONS INDUCED ELECTRONIC STATE TRANSITION

以半经典量子力学方法发展了一个广义的理论，用来描述分子间长程作用下碰撞导致的电子态跃迁过程。运用分子间特别是线性分子间的一级静电Ｈａｍｉｌｔｏｎｉａｎ推导碰撞导致的电子态跃迁矩阵元的表达式，分别考虑了共振和近共振两种能量转移的情形，获得了对应于电子和分子转动运动的选律。

ased on semiclassical quantum mechanical theory, the collisioninduced transition of electronic states under longrange interactions is studied. Using first order electrostatic interaction Hamiltonian especially of linear molecules, the matrix elements expression of collisioninduced electronic transition is derived. The selection rule of the electronic and molecular rotation is derived respect to resonant and quasiresonant energy transfer. Finally the formula is applied to the calculatiion of the \%E\%\++\-\{0g\} and \%D\%\++\-\{0u\} ionpair state in the collisioninduced E region of iodine.
