Description
We review some of the few available nonadiabatic calculations of dipole moments. We show that those carried out in a laboratory-fixed set of coordinate axes are bound to fail and discuss the more reasonable ones in a molecule-fixed reference frame. For completeness we also describe the standard Born--Oppenheimer calculations of dipole moments. We briefly address the experimental estimation of dipole moments from the Stark shift of spectral lines and argue that it does not provide such property but a sort of energy--weighted average of dipole transition moments.
