Abstract
In this paper, we obtain analytical vibrational partition function with recent energy spectrum of the deformed hyperbolic barrier potential. We derive different thermodynamic properties for the RbH, NaK, KRb, NI, 7Li2 and N2 diatomic molecules. In addition, we obtain the total molar entropy for the two last molecules. Our results are in excellent agreement with the experimental data.
