English: The Lennard-Jones 6-12 potential approximates the intermolecular interactions of two atoms due to Pauli repulsion and London dispersion attraction. The potential is defined in terms of the well-depth (${\displaystyle \epsilon }$) and the intercept (${\displaystyle \sigma }$). Other formulations use the radius where the minimum occurs, ${\displaystyle R_{min}}$, instead of ${\displaystyle \sigma }$.
