Kihara potential
From SklogWiki
The Kihara potential, developed by Taro Kihara
\[\Phi_{12}(\rho)=\Phi_0 \left[\frac{m}{n-m}\left(\frac{\rho_{0}}{\rho}\right)^n-\frac{n}{n-m}\left(\frac{\rho_{0}}{\rho}\right)^m\right], ~~~ n>m>3.\]
where \(\Phi_{12}\) is the intermolecular pair potential, and \(\rho\) is the shortest distance between molecule cores.
