Hyperfine structure of the first rotational level in H, D and HD molecules and the deuteron quadrupole moment
Mariusz Puchalski, Jacek Komasa, Krzysztof Pachucki
We perform the four-body calculation of the hyperfine structure in the first rotational state of the H, D, and HD molecules and determine the accurate value for the d…
Second virial coefficients for helium-4 and helium-3 from accurate relativistic interaction potential
Paweł Czachorowski, Michał Przybytek, Michał Lesiuk +2
The second virial coefficient and the second acoustic virial coefficient for helium-4 and helium-3 are computed for a wide range of temperatures (0.5 - 1000K) using a highly accura…
Hyperfine structure in the HD molecule
Jacek Komasa, Mariusz Puchalski, Krzysztof Pachucki
We investigate interactions between the proton spin, the deuteron spin, and the orbital angular momentum in the electronic ground state of the HD molecule. These interactions lead…
Rovibrational energy levels of the hydrogen molecule through nonadiabatic perturbation theory
Jacek Komasa, Mariusz Puchalski, Paweł Czachorowski +2
We present an accurate theoretical determination of rovibrational energy levels of the hydrogen molecule and its isotopologues in its electronic ground state. We consider all signi…
Dissociation Energy of Molecular Hydrogen Isotopologues
Mariusz Puchalski, Jacek Komasa, Anna Spyszkiewicz +1
The nonrelativistic energy together with relativistic and quantum electrodynamic corrections for all the molecular hydrogen isotopologues (D, T, HD, HT, DT) were evaluated…
Relativistic corrections for the ground electronic state of molecular hydrogen
Mariusz Puchalski, Jacek Komasa, Krzysztof Pachucki
We recalculate the leading relativistic corrections for the ground electronic state of the hydrogen molecule using variational method with explicitly correlated functions which sat…
