Effects of electrostatic interactions on orientational order of solutes in nematic solvents: NMR experiments and theoretical predictions
The orientational order parameters of four aromatic solutes in nematic solvents, derived from proton dipolar couplings in NMR spectra, show a correlation with the dielectric anisotropy of the solvents. Explanation of the experimental behaviour is provided by a molecular theory based on the reaction field approximation.
