Superiority of hulburt-hirschfelder function to some three constant potential energy functions

Considering the merits of the five parameter Hulburt-Hirschfelder potential in reproducing the true potential energy curve for diatomic molecules, its predictive reliability of some molecular constants has been investigated by incorporating the modifications of H-H function suggested by Tawde Katti. Results of a/sub e/ and w/sub e/ x/sub e/ obtained here show that the performance of H-H function is consistent with the earlier findings of Steele et al
