Zusammenfassung:In this paper, the energy spectra of the general molecular potential are obtained using the asymptotic iteration method within the framework of non-relativistic quantum mechanics.With the energy spectrum obtained, the vibrational partition function is calculated in a closed form and is used to obtain an expression for other thermodynamic functions such as vibrational mean energy U , vibrational mean free energy F , vibrational entropy S and vibrational specific heat capacity C . These thermodynamic functions are studied for the electronic state X 1 Σ g + of K 2 diatomic molecules.
