A very routine but carefully prepared exercise in application of
exact (viz., Gauss hypergeometric) solvability of radial
Schr\"{o}dinger equations with Kratzer and modified Kratzer
phenomenological potentials to evaluation of matrix elements needed,
ini principle, for description of diatomic (viz., CO and NO)
molecules. The sampled numerical results agree with the samples
available in the literature.
