  Chirality and chiral molecules are key elements in modern chemical and
biochemical industries. Individual addressing, and the eventual separation of
chiral enantiomers has been and still is an important elusive task in molecular
physics and chemistry, and a variety of methods has been introduced over the
years to achieve this goal. Here, we theoretically demonstrate that a pair of
cross-polarized THz pulses interacting with chiral molecules through their
permanent dipole moments induces an enantioselective orientation of these
molecules. This orientation persists for a long time, exceeding the duration of
the THz pulses by several orders of magnitude, and its dependency on
temperature and pulses' parameters is investigated. The persistent orientation
may enhance the deflection of the molecules in inhomogeneous electromagnetic
fields, potentially leading to viable separation techniques.
