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##?
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+.
Isotopes are atoms of the same element that have the same number of protons but different numbers of neutrons. This results in isotopes having different atomic weights.
Isotope measurements allow scientists to determine the composition and structure of molecules. By measuring the ratios of different isotopes in a molecule, scientists can gain insight into its origin, formation, and chemical reactions.
Isotope measurements are typically performed using mass spectrometry, a technique that separates and measures the masses of different isotopes in a sample. Other methods include nuclear magnetic resonance (NMR) spectroscopy and infrared (IR) spectroscopy.
Isotope fractionation refers to the natural process of separating isotopes in a molecule due to differences in their physical or chemical properties. This can provide valuable information about the conditions and processes involved in the formation of the molecule.
Isotope measurements have a wide range of applications in various fields, including geology, biology, environmental science, and forensics. They can be used to study climate change, trace the movement of pollutants, and identify the source of a substance.
