非对称陀螺分子在平行电场和非共振laser场中的转动动力学

Rotational dynamics of an asymmetric top molecule in parallel electric and non-resonant laser fields

Juan J. Omiste, Rosario González-Férez

摘要:

本文对非对称陀螺分子在电场和平行非共振线偏振激光脉冲作用下的转动动力学进行了理论研究。在刚性转子近似下求解了含时薛定谔方程。使用苯甲腈分子为原型,我们调查的实验可访问的场配置的场修饰动力学,并比较这些结果的绝热预测。我们发现,对于一个不对称的顶部分子在平行的领域,形成的摆动双峰和相邻的水平之间避免交叉的非绝热效应的两个主要来源。我们还提供了实现绝热动力学的场参数。

英文摘要:

We present a theoretical study of the rotational dynamics of asymmetry top molecules in an electric field and a parallel non-resonant linearly polarized laser pulse. The time-dependent Schrödinger equation is solved within the rigid rotor approximation. Using the benzonitrile molecule as prototype, we investigate the field-dressed dynamics for experimentally accessible field configurations and compare these results to the adiabatic predictions. We show that for an asymmetric top molecule in parallel fields, the formation of the pendular doublets and the avoided crossings between neighboring levels are the two main sources of non-adiabatic effects. We also provide the field parameters under which the adiabatic dynamics would be achieved.
