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

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.
