Hello! Is there any measurement (can be from different papers/experiments) of a diatomic molecular isotopic chain (i.e. at least 3 isotopes of a given nucleus) where the ground state is ##^{2}\Sigma##?

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.

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.
 
They would be singlets, wouldn't they? You want something like H2+.

That's also true (honestly I would prefer something bigger than hydrogen, tho)
 
From the BCS theory of superconductivity is well known that the superfluid density smoothly decreases with increasing temperature. Annihilated superfluid carriers become normal and lose their momenta on lattice atoms. So if we induce a persistent supercurrent in a ring below Tc and after that slowly increase the temperature, we must observe a decrease in the actual supercurrent, because the density of electron pairs and total supercurrent momentum decrease. However, this supercurrent...
