Query: Comment on: "Interaction of the magnetic quadrupole moment of a
  non-relativistic particle with an electric field in a rotating frame. Ann.
  Phys. 412 (2020) 168040''   We analyze a recent treatment of the interaction of a magnetic quadrupole
moment with a radial electric field for a non-relativistic particle in a
rotating frame and show that the derivation of the equations in the paper is
anything but rigorous. The authors presented eigenvalues and eigenfunctions for
two sets of quantum numbers as if they belonged to the same physical problem
when they are solutions for two different models. In addition to it, the
authors failed to comment on the possibility of multiple solutions for every
set of quantum numbers.
