Ikot et al. (Indian J Phys 93:1171, 2019) showed an analytical solution of the stationary Schrodinger equation for cesium dimers Cs2 at the electronic state (33Σg+) with the shifted Tietz–Wei potential. We point out, however, a miscalculation in solving this equation which had led to erroneous conclusions, particularly about the energy eigenvalues, the partition function and all derived thermodynamic properties. By the way, we present the right expression of the rotational–vibrational energy which shows an excellent agreement with the experimental data.
