The Generalized exponential model (or GEM-m potential) is given by (Eq. x in [1]):
![{\displaystyle \Phi _{12}(r)=\epsilon \exp \left[-\left({\frac {r}{\sigma }}\right)^{m}\right]}](https://wikimedia.org/api/rest_v1/media/math/render/svg/398a7b3390b36654b53354a0f4533487e6865ecc)
where
- is the intermolecular pair potential between two particles or sites
m=1[edit]
Also known as the EXP model [2].
