在被称为光电子圆二色性的手性光学现象中，已经发现通过圆偏振光脉冲从手性分子电离的电子的角分布相对于光传播的方向是反对称的。为了研究这一现象，我们在实验室用飞秒激光对手性分子进行了多光子电离。使用一个简单的立体检测设置，直接测量的不对称性的示例性芳香族手性分子1-苯基乙醇，使用260 nm的脉冲产生的速率为1 MHz。发现不对称性与Stokes的3参数呈线性关系，表明光电子圆二色性是由分子激发态的单光子过程引起的。这是在对比樟脑，其中一个更复杂的依赖于S 3建议，具有一定取向的分子的选择性激发是有影响力的先前和新的结果。
In the chiro-optical phenomenon known as photoelectron circular dichroism, the angular distribution of electrons ionized from chiral molecules by circularly polarized light pulses has been found to be anti-symmetric with respect to the direction of the light propagation. To study this phenomenon, chiral molecules were multiphoton ionized with a femtosecond laser in our laboratory. Using a simple stereo-detection setup, direct measurements of the asymmetry for the exemplar aromatic chiral molecule 1-phenylethanol were made using 260 nm pulses produced at a rate of 1 MHz. It was found that the asymmetry had a linear dependence on Stokes' S 3 parameter indicating that the photoelectron circular dichroism is due to a single photon process from the excited state of the molecule. This is in contrast to previous and new results for camphor where a more complex dependence on S 3 suggested that selective excitation of molecules with certain orientations was influential.
