摘要：

The rovibrational intervals of the He42+ molecular ion in its X ς2u+ ground electronic state are computed by including the nonadiabatic, relativistic, and leading-order quantum-electrodynamics corrections. Good agreement of theory and experiment is observed for the rotational excitation series of the vibrational ground state and the fundamental vibration. The lowest-energy rotational interval is computed to be 70.937 69(10) cm-1 in agreement with the most recently reported experimental value, 70.937 589(23)(60)sys cm-1 [L. Semeria et al., Phys. Rev.
