| Summary: | Phys. Rev. A 104, 032806 (2021) We reconsider the calculation of rovibrational transition frequencies in
hydrogen molecular ions. Some previously neglected contributions, such as the
deuteron polarizability, are included into consideration in comparison with our
previous work. In particular, one-loop and two-loop QED corrections at
$m\alpha^7$ and $m\alpha^8$ orders are recalculated in the framework of the
adiabatic approximation, with systematic inclusion of corrections associated
with vibrational motion. Improved theoretical transitions frequencies are
obtained and found to be in very good agreement with recent high-precision
spectroscopy experiments in HD$^+$. New values for the $m_p/m_e$ and $m_d/m_p$
mass ratios are determined. |
