we argue that the pseudoharmonic potential provides an unsuitable description of the interatomicpotential-energy function of a diatomic molecule because of its wrong behaviour at origin and infinityand because it does not predict dissociation. in addition to it, the level spacing stemming from thismodel does not match the well known vibration-rotation spectrum of a diatomic molecule. we alsoshow that the author derived a nonsensical nonrelativistic schrödinger equation for a diatomicmolecule in a magnetic field and failed to solve it correctly. the dependence of the resulting energylevels on the angle between the vector position and the magnetic field is a result of a gross mistake.
