Morse

[classi] [classj] morse [eps] [rho] [r_e]

$\displaystyle U_{\mathrm{Morse}} = \epsilon \left[1 - \exp\left\{ -\rho \left(r - r_e\right) \right\} \right]^2 - 1$ (8)

where $ \epsilon$ is the energy scale, $ \rho$ is the range parameter, and $ r_e$ is the equilibrium bond distance (or length scale).
