论文摘要
使用微波测量循环三态构型，通过直接的单光子耦合和有效的两光耦合之间的两路干扰进行对映异构体选择性状态转移〜（ESST）。两个对映异构体之间的单相过程中的$π$ - 相差异使一个对映异构体的干扰建设性，但对另一个对映异构体具有破坏性。因此，只有一个对映异构体被激发到更高的旋转状态，而另一个仍处于基态。该方案在脉冲波形和两个路径的时间顺序中具有灵活性。我们在环己基甲醇〜（c $ _7 $ h $ _ {14} $ O）分子的样本中模拟该方案。模拟结果表明，当考虑实验问题时，可以获得鲁棒和高保真。最后，我们建议采用完成的ESST实施对映射分离并确定对映体的过剩。
With a microwave-regime cyclic three-state configuration, an enantiomer-selective state transfer~(ESST) is carried out through the two-path interference between a direct one-photon coupling and an effective two-photon coupling. The $π$-phase difference in the one-photon process between two enantiomers makes the interference constructive for one enantiomer but destructive for the other. Therefore only one enantiomer is excited into a higher rotational state while the other remains in the ground state. The scheme is of flexibility in the pulse waveforms and the time order of two paths. We simulate the scheme in a sample of cyclohexylmethanol~(C$_7$H$_{14}$O) molecules. Simulative results show the robust and high-fidelity ESST can be obtained when experimental concerns are considered. Finally, we propose to employ the finished ESST in implementing enantio-separation and determining enantiomeric excess.
