This was funded by the MEC (Spain) under Projects No. CTQ2005-09185-C02-02, No. FIS2004-02461, and No. FIS2007-65382 and supported by Grants No. BES-2006-11976 (P.B.) and No. BES-2006-7454 (R.P.deT.).A proposal is made to measure the parity-violating energy difference between enantiomers of chiral molecules by modifying the dynamics of the two-state system using an external chiral field, in particular, circularly polarized light. The intrinsic molecular parity-violating energy could be compensated by this external chiral field, with the subsequent change in the optical activity. From the observation of changes in the time-averaged optical activity of a sample with initial chiral purity and minimized environment effects, the value of the intrinsic parity-violating energy could be extracted. A discussion is made on the feasibility of this measurement.engjournal articlehttp://dx.doi.org/10.1103/PhysRevA.80.012110http://www.aps.org/open access535Energy differenceWeak-interactionsPolarized-lightElectric-fieldQuantum beatsEnantiomersSpectroscopyConservationHandednessClustersÓptica (Física)2209.19 Óptica Física
