200-100 Lennard-Jones potential
From SklogWiki
The 200-100 Lennard-Jones potential
\[ \Phi_{12}(r) = 4 \epsilon \left[ \left(\frac{\sigma}{r} \right)^{200}- \left( \frac{\sigma}{r}\right)^{100} \right] \]
where
- \(r := |\mathbf{r}_1 - \mathbf{r}_2|\)
- \( \Phi_{12}(r) \) is the intermolecular pair potential between two particles or sites
- \( \sigma \) is the diameter (length), i.e. the value of \(r\) at which \( \Phi_{12}(r)=0\)
- \( \epsilon \) is the well depth (energy)
