A Fast Fourier Transform Study of the Proton and Deuteron Line Shapes of Some Selected Nematics

Abstract
Proton and deuteron Fourier transform magnetic resonance spectra are reported for a variety of nematic liquid crystals. We discuss the widening of the dipolar splittings of phenylene protons due to terminal proton groups, which results in the incorrect measurements of the degree of order. 'Fine structure' in the proton spectra is related to the rotating methyl groups.
