A generalized morse analytical function for the ``true`` diatomic potential of the RKR type

Technical Report:

Abstract

The problem of the representation of the RKR (or IPA) diatomic potential by a simple analytical function is considered. This old problem has for a fairly good solution the Morse-like function. The problem of the determination of the disposable parameters is reduced to that of a set of linear equations where a standard leas-squares technique is used. This approach shows the same success for deep and shallow potentials. The comparison of the computed E{sub v} (vibrational energy) and B{sub v} (rotational constant) with their corresponding experimental values shows that a good agreement is reached even for high vibrational levels close to the dissociation. 16 refs, 1 fig., 8 tabs.
