The Stockmayer potential is a mathematical model used in molecular simulations to describe the interaction between polar molecules. It is a modification of the Lennard-Jones potential, incorporating an additional term to account for the dipole-dipole interactions present in polar substances. The Stockmayer potential \( U(r) \) typically combines a Lennard-Jones term, representing the van der Waals forces, with a dipole-dipole interaction term.
