We show that the parameters 
and 
in the screened Kratzer potential are not the actual equilibrium bond length and dissociation energy, respectively. Consequently, it makes no sense to apply this form of the model to the spectroscopy of diatomic molecules. We prove that the calculation of the canonical partition function is incorrect because the authors omitted the sum over the rotational quantum number. For this reason, the resulting thermodynamic functions are of no practical utility whatsoever.
