Anti-Morse potential

Empirical methods for calculation of PES are reduced to the specification of the functional form of the PES and determination of the eorresponding parameters from spectroscopie, kinetic, and other experiments. Empirical methods are based on a set of model potentials. The elements of this set are potentials of diatomic fragments. Among the most popular potentials are the Lennard-Jones, Buckingham, Morse, and anti-Morse potentials. We present the Buekingham potential as an example... 

The above result is now used semi-empirically by identifying with the experimentally obtained bonding and AB with the antibonding states. Usually these are taken to be Morse and anti-Morse potentials, i.e.,... 

The VB potential surfaces 1E and 3 7s can be approximated by analytical Morse and anti-Morse functions ... 

When the minimum of a predominantly repulsive potential curve is considered negligible, it may be represented by a so-called anti-Morse curve ...
