In an ideal gas there are no intermolecular interactions. However, in an imperfect or real gas, this is not so, and the second virial coefficient is other than zero. Mayer and Mayer developed a theoretical treatment of the virial coefficients in terms of cluster integrals.
The simplest cluster is that consisting of a single molecule, not bound to any other. A cluster of three specified molecules, i, j and k may be formed in any of four ways:
