This study adopts the improved model Pὂschl-Teller potential to examine the internal vibration of three diatomic molecules. The analytical expressions that predicted molar enthalpy, heat capacity and molar Gibbs free energy were obtained. Using the various molar predicted equations, numerical values for enthalpy, heat capacity and Gibbs free energy were generated for fluorine molecule, iodine molecule, chlorine molecule, phosphorus molecule and potassium molecule. A model equation to check the proximity of the predicted results to the experimental data was obtained. This equation was used to obtain the average absolute percentage deviation of the predicted result from the observed data recorded in National Institute of Standards and Technology data base. The results for all the molecules exhibit remarkable consistency with the observed data. © The Author(s), under exclusive licence to Società Italiana di Fisica and Springer-Verlag GmbH Germany, part of Springer Nature 2024.
