Thermodynamic Properties for the Carbon Monoxide Molecule under the Influence of the Coulomb-Hulthen-Pöschl-Teller Potential

Abstract

In this study, we obtained the approximate l-states solutions of the
Schrödinger equation interacting with a newly proposed potential known
as the Coulomb-Hulthen-Pöschl-Teller (CHPT) by employing the
parametric Nikiforov-Uvarov method. The analytical expressions for the
energy eigenvalue as well as the vibrational mean energy, vibrational
specific heat, vibrational free energy, and vibrational entropy for
