The formula proposed recently by Vuks for the polarization field associated with strongly anisotropic organic molecules has been applied to evaluate the orientational order in p-azoxyanisole, p-azoxyphenetole and their mixtures in the nematic phase. It is found to yield accurate results as is confirmed by the internal consistency of the calculations. The degree of order S plotted against the relative temperature (Tc - T) gives a set of nearly parallel curves, and for a given relative temperature, S is greater the higher the nematic liquid transition point Tc. The degree of order in the mixture is expressible as p1 SPAA+ p2SPAP where p1, p2 are the mole fractions of the pure compounds.
