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 different 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.
