The surface order parameter Ss has been determined for various liquid crystals on a number of substrates. Besides, the influence of a magnetic field on the in plane orientation of the liquid crystal has also been studied. Combination of the data of these experiments leads to a model in which the in plane rotation of a wall adherent liquid crystal layer is described as a function of Ss.Le paramètre d'ordre superficiel Ss a été obtenu pour différents cristaux liquides et pour un certain nombre de substrats. Par ailleurs l'influence d'un champ magnétique sur l'orientation du cristal liquide à la surface du substrat a été étudiée. En utilisant une combinaison des données obtenues par ces deux études, il a été possible de réaliser un modèle dan...
