The largest hyperfine interaction coefficients in the hydrogen molecular ion , i.e., the electron-proton and electron-deuteron spin-spin scalar interactions, are calculated with estimated uncertainties slightly below 1 ppm. The relativistic correction for which a detailed derivation is presented, QED corrections up to the order along with an estimate of higher-order terms, and nuclear structure corrections are taken into account. Improved results are also given for the electron-proton interaction coefficient in , in excellent agreement with rf spectroscopy experiments. In , a difference is found in the hyperfine splitting of the two-photon transition that was recently measured with high precision. The origin of this discrepancy is unknown.
