m-6-8 potential function
The m-6-8 potential function  is given by (Eq. 1)
where and is the intermolecular pair potential between two particles or sites. is the coefficient corresponding to the repulsive term, and and are the coefficients corresponding to the attractive inverse sixth and eighth powers respectively.
This expression can be rewritten in the reduced form (Eq. 2):
where , and . is the "well" depth, and is the intermolecular separation at the maximum well depth.
