Various methods for representation of electronic states in diatomic molecules basing on experimental spectroscopic data are critically compared. The technique of point wise inverted perturbation approach (IPA) is indicated as the most suitable in case of states characterized by potential energy curves substantially different from the Morse potential. Recent developments of this technique are presented.
