    Description / Table of Contents: The 240 MHz NMR spectra of bipyrimidine in the nematic phase of p-methoxybenzylidene-p-n-butylaniline is analysed. The para H,H inter-ring distance is determined. The barrier to internal rotation of the inter-ring C—C bond is studied. Excellent agreement between experimental and calculated spectra is obtained using potential function V(φ) = ½ ΣNVn (1 - cosn φ) with V1 = V2 = V3 = 0 cal mol-1 and V4 = 500 cal mol-1.
    Notes: Le spectre de RMN obtenu à 240 MHz pour la bipyrimidine orientée dans un solvant nématique p-métoxybenzylidène p-n-butyl aniline est analysé. La distance entre les hydrogènes en position para est déterminée. La barrière de potentiel s'opposant à la libre rotation autour de la liaison centrale C—C est étudiée. Un excellent accord est obtenu entre spectre calculé et spectre expérimental lorsqu'on utilise une fonction potentielle V(φ) = 1/2 ΣNVn (1 - cosn φ) avec V1 = V2 = V3 = 0 cal mol-1 et V4 = 500 cal mol-1.
