Abstract

Lee-Goldburg decoupling has been applied to enhance dipolar oscillations during the t1 period of the two-dimensional experiment used for obtaining order parameters of the liquid crystal N-(4-ethoxybenzylidene)-4-n-butylaniline (EBBA) at different temperatures. The order parameters of the aromatic core obtained by this method are in agreement with values obtained from the 2H NMR spectra of a selectively labelled compound and are observed to follow the empirical Haller equation.
