摘要:

在量子力学处理的分子与经典光场相互作用的框架内,提出了光修饰分子的旋振光谱理论。数值计算结果表明,对于均质双原子分子Na $_2$,其通式可以大大简化,导致光修饰谱的物理过程也可以直接理解.给出了Na $_2$光修饰谱中不同峰的物理来源,并从光修饰谱与修饰场强度、波长、修饰场开启时间和温度的关系等方面进行了研究。本文还讨论了光缀饰光谱在推导无场光谱量方面的重要意义。

英文摘要:

The theory of rovibronic spectroscopy of light-dressed molecules is presented within the framework of quantum mechanically treated molecules interacting with classical light fields. Numerical applications are demonstrated for the homonuclear diatomic molecule Na$_2$, for which the general formulae can be simplified considerably and the physical processes leading to the light-dressed spectra can be understood straightforwardly. The physical origin of different peaks in the light-dressed spectrum of Na$_2$ is given and the light-dressed spectrum is investigated in terms of its dependence on the dressing field's intensity and wavelength, the turn-on time of the dressing field, and the temperature. The important implications of light-dressed spectroscopy on deriving field-free spectroscopic quantities are also discussed.
