We propose an analytical five-parameter potential function for stable diatomic molecules V(x) = K/x3 − e−tx(a + bx + cx2). Here x = r/re, where r is the internuclear distance and re the equilibrium bond length. K, t, a, b, c are five parameters of the function, which are obtained from molecular spectroscopic data in terms of known molecular constants.
Nous proposons une fonction potentielle analytique à cinq paramètres pour des molécules diatomiques stable: V(x) = K/x3 − e−tx(a + bx + cx2). Ici, x = r/re, r est la distance internucléaire, et re est la longueur de lien d'équilibre. K, t, a, b, c sont les cinq paramètres de la fonction, qui sont obtenus de données spectroscopiques moléculaires en termes des constantes moléculaire connues.
Key words: Analytical Potential Function, Empirical Model, Potential Function, Diatomic Molecule.
