The most common potential to model the Van der Waals interactions is known as the Lennard-Jones potential. The Lennard-Jones potential is a mathematically simple model that approximates the interaction between a pair of neutral atoms or molecules. A form of this interatomic potential was first proposed in 1924 by John Lennard-Jones. The most common expressions of the L-J potential are where is the depth of the potential well, is the finite distance at which the inter-particle potential is zero, is the distance between the particles, and is the distance at which the potential reaches its minimum. Due to its computational simplicity, the Lennard-Jones potential is used extensively in computer simulations even though more accurate potentials exist. (from wikipedia)
