Recent advances in quantum electrodynamic theory and computational techniques for diatomic molecular systems make available the very accurate theoretical predictions for the hydrogen molecule and its isotopomers. Apart from testing fundamental interactions at the atomic scale, comparison with experimental values for rovibrational levels indicates limited applicability of the relativistic quantum chemistry and demonstrates the importance of QED effects. I will review recent progress in the theoretical description of simple molecular systems and present comparison with the most recent measurements performed at ETH Zurich and VU University of Amsterdam.
