The structure of ethylbenzene as a solute in liquid crystalline solvents ia analysis of proton NMR spectra
Abstract
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.
