The discussion revolves around the measurement of isotopes in diatomic molecular isotopic chains, specifically focusing on cases where the ground state is ##^{2}\Sigma##. Participants explore existing data, calculations, and the relevance of these molecules in the context of neutrino mass measurements.
Participants have not reached a consensus on the availability of measured data versus calculated data for the isotopes in question, and there is a divergence in preferences regarding the size of the molecules discussed.
The discussion highlights a lack of clarity regarding the distinction between measured and calculated data, as well as the specific molecular parameters needed for the inquiry.
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+.
