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~(C7H14O) 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.

手性分子对映体选择性状态转移的两径干扰

在微波状态下的环状三态构型下,对映体选择性状态转移(ESST)是通过直接单光子耦合与有效两光子耦合之间的两路径干涉来进行的。的π两个对映体之间的单光子过程中的相差使得干涉对一种对映体是有益的,而对另一种对映体是有害的。因此,仅一种对映体被激发成更高的旋转状态,而另一种对映体保持基态。该方案在脉冲波形和两条路径的时间顺序方面具有灵活性。我们在环己基甲醇〜(C7H14O)分子。仿真结果表明,考虑到实验问题,可以获得强大而高保真的ESST。最后,我们建议使用完成的ESST进行对映体分离和确定对映体过量。
