Thermodynamic Properties of Diatomic Molecules: A Jost Function Approach
DOI:
https://doi.org/10.15407/ujpe71.8.641Keywords:
Jost function, diatomic molecule, partition function, internal energy, free energy, specific heat, entropyAbstract
A differential equation approach was employed to derive the necessary expression for the regular solution. By utilizing the interplay between the regular solution, the irregular solution, and the Jost function, the Jost function for the Manning–Rosen potential was constructed in its most reduced form. This Jost function was then applied to investigate the bound state energies and thermodynamic properties of both homonuclear and heteronuclear diatomic molecules.
