## Abstract Proton NMR spectra 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 a
