The Lennard-Jones Potential V is the intermolecular potential between the two atoms or molecules. ϵ is the well depth and a measure of how strongly the two particles attract each other. σ is the distance at which the intermolecular potential between the two particles is zero (Figure 1 ).

The Lennard-Jones potential is a relatively-simple mathematical model describing the potential energy $V_{LJ}$ between a pair of neutral atoms as a function of both the distance in units of radii where the potential is zero $\sigma$ (sigma) and the maximum depth of the potential well $\varepsilon$ (epsilon). Equation 1: The Lennard-Jones potential. The LJP model is composed of two components: the repulsive (σ/r)¹² and the attractive term (σ/r)⁶, which respectively denote repulsive and attractive forces. The parameter r is the distance between the two atoms (in Å units); A potential used to give an approximate description of the potential energy interaction, V, of molecules as a function of intermolecular distance r.

It was proposed in 1924 by John Lennard-Jones. The L-J potential is of the form. The Lennard-Jones 12-6 potential (LJ) is arguably the most widely used pair potential in molecular simulations. In fact, it is so popular that the question is rarely asked whether it is fit for purpose. In this paper, we argue that, whilst the LJ potential was designed for noble gases such as argon, it is often used for systems where it is not The potential functions can be subdivided into three parts Non-bonded : Lennard-Jones or Buckingham, and Coulomb or modified Coulomb. The non-bonded interactions are computed on the basis of a neighbor list (a list of non-bonded atoms within a certain radius), in which exclusions are already removed. Code 1: Calculating the Lennard-Jones Potential.

The formulas are based on the description of two-body energy contributions by an inverse power expansion (extended Lennard-Jones potential). The Lennard-Jones potential (also termed the LJ potential or 12-6 potential) is an intermolecular pair potential.
