Electron-nucleus Araki-Sucher correction in the hydrogen molecule isotopologues
Jacek Komasa
The quantum electrodynamic Araki-Sucher correction arising from the interaction between electrons and nuclei is calculated for rovibrational energy levels of the hydrogen molecule…
Integrals for relativistic nonadiabatic energies of H in exponential basis
Krzysztof Pachucki, Jacek Komasa
Accurate predictions for hydrogen molecular levels require the treatment of electrons and nuclei on an equal footing. While nonrelativistic theory has been effectively formulated t…
Nonrelativistic energy of tritium-containing hydrogen molecule isotopologues
Krzysztof Pachucki, Jacek Komasa
The nonrelativistic energy of low lying rovibrational levels of HT, DT, and \T\ is determined to an absolute accuracy of cm using the variational method wi…
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…
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…
