Theoretical prediction of thermodynamic properties of N2 and CO using pseudo harmonic and Mie-type potentials

Abstract In this work, thermodynamic properties of nitrogen (N2) and carbon monoxide (CO) were theoretically predicted by using two potential models, pseudo harmonic and Mie-type. We have solved the Schrodinger equation for the potential models and obtained the analytical expressions for energy eigenvalues. Using the energy spectra, partition function and thermodynamic properties of N2 and CO were calculated. Examples of the thermodynamic properties are specific heat at constant pressure, entropy and enthalpy. According to the obtained results, it is found that there is good agreement between our theoretical results and experimental data.
