Previously we have determined the dilute mixture transport properties of slightly polar fluorocarbons using the inverted intermolecular potential energies (Ind. Eng. Chem. Res. 45 (2006) 9211-9223). In the present paper

the corresponding states correlations for reduced viscosity collision integrals were employed to obtain effective unlike interaction potential models for dilute binarymixtures of highly polar molecule ammonia with noble gases. The inverted potentials were fitted to the Morse-Spline-van der Waals (MSV)

model potential. The method of least-squares fitting was then applied to identify best consistence force parameters for each ammonia-noble gas mixture

taking advantage of experimental viscosities

diffusion coefficients and thermal conductivities. The proposed potential modelswere compared with those obtained fromother sources

in order to assess the extent of their validity. The potentials were later employed to calculate transport properties of the studied mixtures. Then

results were compared with those reported in the literature

which led to the acceptable agreement.
