A recently developed renormalization group theory of condensable gases that takes into account short range attractive intermolecular forces is successful in describing the thermal properties of real fluids both at the critical point and in a large adjoining neighborhood. The theory has been tested for a variety of models, and for real gases such as argon and ethane. In its simplest form, the theory employs three free parameters - attraction constant a, hard core volume b, and cohesion volume c of the molecules. These parameters can be calculated from the theory and the authors have done so using Lennard-Jones and Yukawa potentials with hard cores. A brief review of the theory will be presented and results discussed.
