Lennard-Jones Potential:

Failed to parse (Conversion error. Server ("https://wikimedia.org/api/rest_") reported: "Cannot get mml. Server problem."): {\displaystyle V(r)=4\epsilon \left[\left({\frac {\sigma }{r}}\right)^{12}-\left({\frac {\sigma }{r}}\right)^{6}\right]}

where:

V(r): Potential energy of interaction betweeen two particles at a distance r;

σ: Diameter (length);

ε: well depth (energy)
