Abstract

 

Homo- chiral dimers (R - R) and (S - S) and hetero- chiral dimers (R - S) obey opposite selection rules, in regard to their dimer states. Based on that we proposed two simple schemes for purifying scalemic (not 50% - 50%) chiral mixtures.

The first scheme is based on the selective excitation of the target dimers by a single pulse. The second scheme is based on spatial separation of these dimers by a selective laser induced potential. This scheme is executed by a simple coherent control technique, which selectively subjects one of the dimers to a dark (null) potential while the other is subjected to a bright potential. I will present the theoretical background for the selective selection rules of the dimers, and explain the mechanism of selective potentials
