The perturbation theories of fluids allow to describe the behaviour of real gasesand liquids, i.e., of systems with relatively complicated intermolecular interactions, on thebasis of thermodynamic and distribution functions of a simpler system chosen as areference. Hence the perturbation methods are analogous to classical thermodynamictreatments which employ, for the description of real systems, appropriately selectedstandard states together with expressing the excess functions through expansions; for amethod to be successful, the proper choice of the reference and a knowledge of itsbehaviour as accurately as possible are extremely important. Recently there has beenshown no interest in the cyclic molecules because of their complexity to describe thethermodynamic behaviour. In the present theory we made attempts to apply perturbationtheory to cyclic hexamers which could be expected to be useful in the petroleumchemical industry where the aromatic chemicals are commonly treated.
