Abstract
Lee-Goldburg decoupling has been applied to enhance dipolar oscillations du ring the t(1) period of the two-dimensional experiment used for obtaining o rder parameters of the liquid crystal N-(4-ethoxybenzylidene)-4-n-butylanil ine (EBBA) at different temperatures. The order parameters of the aromatic core obtained by this method are in agreement with values obtained from the H-2 NMR spectra of a selectively labelled compound and are observed to fol low the empirical Haller equation.
