论文摘要
我们提出了一对通过一对延迟的交叉偏振飞秒激光脉冲激发的手性分子的对映选择性方向的全面研究。我们表明，通过优化脉冲的参数，可以在零和五个开尔文旋转温度下实现显着（约10％）的对映选择性取向。这项研究提出了一组合理的实验条件，用于诱导和测量强大的对映选择性方向。拟议实验所需的强大对映选择性方向以及稳定的激光系统的广泛可用性可能打开新的途径，以区分和分离分子对映异构体。
We present a comprehensive study of enantioselective orientation of chiral molecules excited by a pair of delayed cross-polarized femtosecond laser pulses. We show that by optimizing the pulses' parameters, a significant (~ 10%) degree of enantioselective orientation can be achieved at zero and at five kelvin rotational temperatures. This study suggests a set of reasonable experimental conditions for inducing and measuring strong enantioselective orientation. The strong enantioselective orientation and the wide availability of the femtosecond laser systems required for the proposed experiments may open new avenues for discriminating and separating molecular enantiomers.
