Morse potential
The empirical function relating the potential energy of a molecule to the inter-atomic distance r accounting for the anharmonicity (See: harmonic approximation) of bond stretching:
Math - e
where Math - ei is the bond-dissociation energy, Math - ei is the equilibrium bond length, and Math - ei is a parameter characteristic of a given molecule.
