  We explore the spatial enantioseparation of gaseous chiral molecules for the
cyclic three-level systems coupled with three electromagnetic fields. Due to
molecular rotations, the specific requirements of the polarization directions
of the three electromagnetic fields lead to the space-dependent part of the
overall phase of the coupling strengths. Thus, the overall phase of the
coupling strengths, which differs with $\pi$ for the enantiomers in the cyclic
three-level model of chiral molecules, varies intensely in the length scale of
the typical wavelength of the applied electromagnetic fields. Under the induced
gauge potentials resulting from the space-dependent part of the overall phase
and the space-dependent intensities of coupling strengths, we further show
spatial enantioseparation for typical parameters of gaseous chiral molecules.
