Abstract
We present quantum dynamical simulations on the axial chiral model system 2,2′-difluoro-biphenyl which supports four stereoisomers, i.e. two diastereomeric pairs of enantiomers, along the torsion around its central C-C bond. A pump-dump control mechanism is developed which consists of stereo-selective, i.e. enantio- and diastereo-selective, ultrashort laser pulses that convert a racemic mixture to one of its diastereomers. For that purpose the enantioselective laser pulse control of previous theoretical investigations is extended for systems that support more than one pair of enantiomers. Still, the polarization of the laser field determines the stereoselectivity of the control mechanism.
