Rational Pulse Design for Enantiomer-Selective Microwave Three-Wave Mixing

Microwave three-wave mixing allows for enantiomer-selective excitation of randomly oriented chiral molecules into rotational states with different energy. The random orientation is reflected in the degeneracy spectrum respect to orientational quantum number M and reduces, if not accounted for, enantiomer-selectivity. Here, we show how design pulse sequences maximal enantiomer-selectivity from an analysis M-dependence Rabi frequencies associated transitions induced by resonant microwave drives. We compare excitations schemes that at a given temperature achieved synchronized circularly polarized fields.
