The **Sutherland potential** ^{[1]}^{[2]} is given by

where is the intermolecular pair potential, is the distance between site 1 and site 2, is the radius of the central hard core, is the energy well depth (), and is a parameter that controls the interaction range. For example, for the potential look like
