Input(s)

в: Potential of Well $(\mathrm{N} \mathrm{m})$

$\sigma$: Collision Diameter $(\mathrm{m})$

r: Distance (m)

Output(s)

phir: Intermolecular potential energy $(\mathrm{N} \mathrm{m})$

Formula(s)

$$ \text { phir }=4 * \varepsilon *\left(\left(\frac{\sigma}{r}\right)^{12}-\left(\frac{\sigma}{r}\right)^{6}\right) $$
