Chiral liquid crystals used as solvents have been shown to be very powerful in giving separate nuclear magnetic resonance (NMR) signals for enantiomers. However, a fundamental problem remains: how to attribute absolute configurations to the various NMR responses? In this paper it is demonstrated that the absolute configuration problem could be solved in predicting the sign of the rotation of the principal axis system of the Saupe matrix in the molecular frame when going from an achiral (racemic) to a chiral anisotropic solvent.
