分子长程作用导致的电子态转移半径典量子理论

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。并将理论表达式用于碰撞导致的碘分子E带E⁺_{0g和D0u^{+离子对态的数值计算。}}

SEMI-CLASSICAL QUANTUM THEORY OF LONG-RANGE INTERACTIONS INDUCED ELECTRONIC STATE TRANSITION

Based on semi-classical quantum mechanical theory, the collision-induced transition of electronic states under long-range interactions is studied. Using first order electrostatic interaction Hamiltonian especially of linear molecules, the matrix elements expression of collision-induced electronic transition is derived. The selection rule of the electronic and molecular rotation is derived respect to resonant and quasi-resonant energy transfer. Finally the formula is applied to the calculatiion of the E⁺_0g and D⁺_0u ion-pair state in the collision-induced E region of iodine.
