The Lennard-Jones potential (LJ) is a simple pair potential that can accurately model weak van der Waals bonds between noble gases, yielding reliable bond energies and bond lengths ( Lennard-Jones 1924 ). The LJ has the form.

The Lennard-Jones potential is a function of the distance between the centers of two particles. When two non-bonding particles are an infinite distance apart, the possibility of them coming together and interacting is minimal. For simplicity's sake, their bonding potential energy is considered zero. However, as the distance of separation ...
