Molecular chirality is an omnipresent phenomenon of fundamental significancein physics, chemistry and biology. For this reason, search for novel techniquesfor enantioselective control, detection and separation of chiral molecules isof particular importance. It has been recently predicted that laser fields withtwisted polarization may induce persistent enantioselective field-freeorientation of chiral molecules. Here we report the first experimentalobservation of this phenomenon using propylene oxide molecules($\mathrm{CH_{3}CHCH_{2}O}$, or PPO) spun by an optical centrifuge - a laserpulse, whose linear polarization undergoes an accelerated rotation around itspropagation direction. We show that PPO molecules remain oriented on a timescale exceeding the duration of the centrifuge pulse by several orders ofmagnitude. The demonstrated long-time field-free enantioselective orientationopens new avenues for optical manipulation, discrimination, and, potentially,separation of molecular enantiomers.
