A spectroscopy scheme is proposed for the detection of the two-photon rotational transition (v,L)=(0,0)→(0,2) and the two-photon rovibrational transition (v,L)=(0,0)→(2,0) of cold trapped HD+ ions by dissociation. The two-photon lineshapes are calculated using a rate equation model. The resolution is at the 10-13 level. The lightshift for selected hyperfine components of the two-photon transitions is evaluated using the two-photon operator formalism. The experimental accuracy with two-photon transitions of trapped HD+ ions is estimated at the 10-12 level, which corresponds also to the accuracy of the theoretical calculations. The comparison of experimental data and theoretical calculations for HD+ and H2+ transitions may lead to an independent determination of the Rydberg constant, the proton-to-electron mass ratio and the deuteron-to-proton mass ratio. It may provide a measurement of the proton and deuteron radii by molecular spectroscopy. Depending on possible issues of the proton radius puzzle in atomic spectroscopy, two-photon spectroscopy of hydrogen molecular ions may lead to an improvement of the determination of the proton-to-electron mass ratio and deuteron-to-proton mass ratio at the 10−12 level.Show less >
