The **Weeks-Chandler-Anderson perturbation theory** is based on the following
decomposition of the intermolecular pair potential (in particular, the Lennard-Jones potential ):

The reference system pair potential is given by (Eq, 4 Ref. 1):

and the perturbation potential is given by (Eq, 5 Ref. 1):
