The modified version of the generalized Mobius square (GMS) potential has been obtained by employing the dissociation energy and equilibrium bond length as explicit parameters. The potential parameters have been defined in terms of the molecular parameters. The modified GMS potential has also been used to model internuclear interaction potential curves for different states of diatomic molecules. Also, we have obtained the rotational–vibrational energy spectra of the new GMS potential model, both analytically and numerically for the different diatomic molecules. This was done by employing a Pekeris-type approximation scheme and an appropriate coordinate transformation to solve the Schrodinger equation. Our results have been compared with the experimental Rydberg–Klein–Rees (RKR) data and its corresponding average absolute deviations in terms of the dissociation energy computed. The effects of the vibrational and rotational quantum numbers on the rotational–vibrational energies for the different states of the various diatomic molecules have also been discussed. This paper has shown to be highly relevant to the studies of thermodynamic and thermochemical functions of diatomic molecules.

Good Agreement

<p>A new principle of steady state of atoms in heteronuclear diatomic molecules based on constraint rule is proposed. Each atom in a heteronuclear diatomic molecule is described by three parameters a, b and ζand the atoms are the most stable when the value ζa/b is constant(2.601824). This model has one free parameter which was fitted by the graphical method.The calculated dissociation energy are in good agreement with the known experimental values.</p>

Accurate Relation

Abstract An accurate relation, connecting dissociation energy D0, force constant for infinitesimal amplitude ke and internuclear equilibrium distance re has been deduced from Varshni and Shukla's potential function. It is of the form D0=ke {A + B re2 + C re4), where A, B and C are constants and are the same for groups of similar diatomic molecules. The values of D0 estimated by this relation are in better agreement with the observed ones than those estimated by Somayajulu, and Tandon et al.

Abstract The observation of the gaseous BiPb molecule [1,2] suggests the existence of heteronuclear diatomic molecules of lead with the group V-b elements. The present paper reports on the identification of the SbPb(g) molecule and the determination of its dissociation energy by mass spectrometric Knudsen-effusion method.
