If the new GeV-scale force-carrier in the model is a non-Abelian gauge boson, then the dark matter will naturally take the form of a multiplet of states, with mass splittings of the order of ...

Unfortunately, many 1H-NMR spectra are severely overlapped due to the multiplet structure caused by homo-nuclear scalar couplings. "Pure shift" NMR spectra, also known as broadband homonuclear ...

This "many-multiplet method" is very complicated, involving a lot of curve fitting, and as a result you can find a lot of people in the literature arguing about whether the shifts people think ...
