The discussion centers on the isotopic measurements of diatomic molecules, specifically those with a ground state of ##^{2}\Sigma##, such as HeH+, HeD+, and HeT+. Participants highlight the significance of these molecules in the context of neutrino mass measurement, particularly in relation to the decay of TH, TD, and T2. Accurate calculations have been referenced from a specific AIP publication, although there is a noted lack of experimental measurements and molecular parameters for the energy levels of these isotopes.
PREREQUISITESResearchers in molecular physics, particle physicists studying neutrinos, and anyone interested in the isotopic behavior of diatomic molecules.
Thank you! But these seems to be calculated not measured? Also they don't list the molecular parameters associated to that energy level, which is what I actually need.DrDu said:I suppose you can find data on HeH+, HeD+ and HeT+.
There are accurate calculations:

These molecules are of great interest, as they form in the decay of TH, TD and T_2 which are intensively studied in the context of measuring the mass of neutrinos.
That's also true (honestly I would prefer something bigger than hydrogen, tho)mjc123 said:They would be singlets, wouldn't they? You want something like H2+.
