三原子分子转动-振动-电子跃迁强度的理论计算方法

Theoretical methods for calculating rotational-vibrational-electronic transition intensities in triatomic molecules

Emil J. Zak

摘要:

这篇文章包括分子转动和振动的量子理论的几个选定的方面。三原子分子是最简单的系统,它表现出较大的多原子分子的定性特征。在最小的三原子分子的例子中,我们展示了几种用于计算高精度的转动振动电子能量,波函数和跃迁强度的理论方法。读者可以把这篇文章看作是一个教程,但决不是全面的,它仍然触及了现代理论分子光谱学中一些未解决的问题。

英文摘要:

This article covers few selected aspects of quantum theory of molecular rotations and vibrations. Triatomic molecules are the simplest systems, which show qualitative characteristics of larger polyatomic molecules. On the minimal example of triatomic molecules we demonstrate several theoretical methods used to calculate highly accurate rotational-vibrational-electronic energies, wavefunctions and transition intensities. The reader can view this article as a tutorial, by no means comprehensive, which still touches some of the unsolved problems in modern theoretical molecular spectroscopy.
