Rotational vibrational partition function using attractive radial potential plus class of Yukawa potential

摘要

We determined the rotational vibrational (RV) partition function from the energy eigenvalues obtained for the attractive radial potential plus class of Yukawa potential (ARPCYP) via asymptotic iteration method (AIM). From these eigenvalue spectrum and RV partition functions, we obtained various thermodynamical properties such as vibrational mean energy (U) and vibrational mean free energy (F).
