Perturbation theory proposed to describe fluids with the multipole interactions was extended to the systems with significant induced interactions. The relations obtained were used to study the effect of the permanent and induced multipole interactions on excess thermodynamic functions of binary solutions formed by a simple fluid (interacting according to the Lennard-Jones pair potential) and a fluid with anisotropic intermolecular forces. Model solutions were studied first; the same procedure was then used to predict behaviour of the real systems cyclopentane-chloroform at 298.15 K and xenon-hydrogen chloride at 195.4 K. A considerable effect of anisotropic interaction on excess quantities of the model- as well as actual solutions was proved.
