Thermal Properties of CO Diatomic Molecule in the Presence of Energy Slope Parameter (ESP)

Abstract

In this research article, thermal properties of energy dependent Kratzer potential (EDKP) for CO diatomic molecule is presented. The non-relativistic energy spectra earlier obtained by Ikot et al. [7] for EDKP was utilized to numerically obtain the partition function. This partition function was then used to obtain the thermal properties (such specific heat capacity, entropy, mean energy and Helmholtz free energy) of this system numerically for negative and positive values of the energy slope parameter respectively. It is observed that the energy slope parameter regulates the behavior of the system for different values. The results of this study will find direct application in molecular physics.
