Effects of the Polarization Force on the Rotational Transition in Polyatomic Molecules by Electron Collision
暂无分享,去创建一个
The rotational excitation of a polyatomic molecule by electron collision is considered as caused by the polarization interaction as well as by the electrostatic one. It is shown how to incorporate the polarization effect into the Born formula previously derived for the rotational cross sections of symmetric-top molecules. Numerical examples are given for the electron-NH 3 , –H 2 O, and –H 2 CO collisions.
