The orientational order and conformational distributions of the two enantiomers in a racemic mixture of a chiral, flexible molecule dissolved in a chiral nematic liquid crystalline solvent

The orientational order and conformational distributions of the two enantiomers of (+/-)-alpha-ethylhexanoic acid-d(15), a flexible chiral molecule, dissolved in a chiral nematic liquid crystalline solvent made of PBLG in an organic co-solvent are obtained by analysis of NMR data. The anisotropic, NMR parameters are obtained from the separated analysis of the two enantiomers using carbon-deuterium, deuterium-deuterium 2D correlation experiments and proton-coupled carbon-13 1D experiments. The analysis of conformational distributions, and the conformationally dependent orientational order parameters are derived using the additive potential, AP, model
