We calculate the DC Stark effect for three molecular hydrogen ions in thenon-relativistic approximation. The effect is calculated both in dependence onthe rovibrational state and in dependence on the hyperfine state. We discussspecial cases and approximations. We also calculate the AC polarisabilities forseveral rovibrational levels, and therefrom evaluate accurately the black-bodyradiation shift, including the effects of excited electronic states. Theresults enable the detailed evaluation of certain systematic shifts of thetransitions frequencies for the purpose of ultra-high-precision optical,microwave or radio-frequency spectroscopy in ion traps.

The static and dynamic polarisability, and the Stark and black-body radiation frequency shifts of the molecular hydrogen ions H2+, HD+, and D2+
