Chirality is a fundamental property of nature. Enantiomers exhibit distinct properties in fields such as biomedicine, and achieving their efficient separation and detection remains a challenge of significant interest in physical chemistry. This report focuses on the enantioseparation of gaseous chiral molecules based on the cyclic three-level model, exploring corresponding schemes for different types of molecules. First, it reveals the characteristics of the “phase mismatching” term as a physical resource for spatial separation in asymmetric top chiral molecules. Second, it proposes a double-loop four-level model for symmetric top chiral molecules to achieve Enantiospecific State Transfer (ESST). Finally, for chiral molecules with low asymmetry, a “pump-control” scheme is designed to achieve high-efficiency ESST. These works provide a theoretical reference for the physical separation of chiral molecules under gas-phase conditions.
