  It is shown that: the analytical solution of the stationary Schrodinger
equation for diatomic molecules with the shifted Tietz-Wei potential, which was
reported in the paper Exact and Poisson summation thermodynamic properties for
diatomic molecules with shifted Tietz potential, A N Ikot, W Azogor, U S
Okorie, F E Bazuaye, M C Onjeaju, C A Onate and E O Chukwuocha, Indian Journal
of Physics, 2019, is incorrect; the analytical expressions for the
rotational-vibrational energy spectrum for diatomic molecule obtained from the
incorrect analytical solution of the Schrodinger equation is incorrect; and
free energy, internal energy, entropy and specific heat of cesium dimer at the
electronic state calculated from the incorrect expression for the
rotational-vibrational energy spectrum are incorrect.
