    Abstract

    Improved values of hyperfine coefficients related to the electronic spin-orbit and electron-nucleus spin-spin tensor interactions in the HD+ molecular ion are obtained through numerical calculation of relativistic corrections at the mα6 order and radiative corrections at the mα7ln(α) order. The theoretical accuracy is improved by more than one order of magnitude. Some deviations with recent high-precision rovibrational spectroscopy experiments are observed, in contrast with the good agreement obtained in H2+.
