dc.description.abstract	Proton NMR speclra of dibenzofuran and dibenzothiophene were investigated in the nematic phase of liquid crystals. Dipolar couplings obtained from the spectral analysis were used to derive the inter-proton distance ratios. Deviations from planarity were observed in both molecules, and an attempt was made to determine the extent of non-planarity. Differences in the relative inter-proton distances in the two molecules are explained in terms of the bond polarization hypothesis and the van der Waah and the covalent radii of the oxygen and sulphur heteroatoms.	en
