Fluids formed by molecules interacting with discrete potentials are examined in the context
of perturbation theory and the reference hypernetted chain equation (RHNC) solution to the
Ornstein—zernike equation. A perturbation theory for discrete-potential fluids (DPT) is
presented, which only requires one to know the properties of a square-well fluid of variable
range. Several potentials are studied: square-shoulder, a combination of a square-well and
square-shoulder, and a discrete representation of a continuous potential model. We have …

Several potentials are studied: square-shoulder, a combination of a square-well and square-shoulder, and a discrete representation of a continuous potential model. We have found that the DPT approach reproduces the RHNC predictions in most of the cases.
