  text: The Haller relationship was applied to estimate the nematic order parameter
    S from 1H NMR spectra of fully protonated liquid crystals aligned in the magnetic
    field. The NMR line shapes were approximated as doublets of very broad peaks.
    Both the temperature-dependent doublet Splitting and the full width at half maximum
    of the whole spectra were used for Haller extrapolation. The order parameters
    obtained with the proposed approach for 4-cyano-4'-pentylbiphenyl (5CB) and the
    nematic mixture E7 were found to be in good agreement with previously reports.
