The structure of ethylbenzene as a solute in liquid crystalline solvents

Previous attempts to analyze the proton spectrum of ethylbenzene as a solute in nematic liquid crystalline
solvents failed, but a successful strategy has now been devised and is described here. The proton spectra of
samples of ethylbenzene dissolved in four di†erent liquid crystals have been analyzed to yield sets of the
partially-averaged dipolar couplings, Dij . The couplings are then used to test models for the structure and
conformation of this molecule.
