Axial Force - Measuring on Ortho and Para Hydrogen and Deutrium

Interesting discovery this weak, ortho and para water (BBC) has been measured for the first time, i was actually thinking about the Axial force after not posting for many years. And it occurs to me that the axial force would lead to there being different energy for either ortho and para hydrogen or ortho and para deuterium. The para molecule has spins on the neuclei in the same direction while the othro molecule has spins on the opposite directory. Since the axial force reverses when the spin on the either a proton or a neutron or both (we don't know which are charge, but we do know by conversion of axial charge in beta decay, that the axial charged it different by one unit of neutrino charge on the proton and neutron, possible charges are (neutron 1, proton 0), (neutron 0, proton -1), (neutron 1/2, proton -1/2). Whatever the charges are, we thus know one of the neutron or the proton has an axial charge, and so the energy of the molecule will different, most probably less in the ortho case, and more in the para case, than the standard model predicts. I asked on Physics Stack Exchange wheather, this could be ditectable, or weather measurement where good enough to rule out an axial force. Rob the moderator, was kind enough to answer, How well are the energy diffences between ortho and para hydrogen and deuterium known, ((License). It seems present state of the art hasn't been very good at measuring or predicting the energy difference, so the axial force is still possible, however a measurement of a anomalous energy difference between ortho and para states would probably be explained by predition errors in the strong force.
