Abstract

The results for nonadiabatic perturbation theory applied to the hydrogen molecule are compared with the direct nonadiabatic calculations with explicitly correlated exponential functions. After including additional of relativistic and quantum electrodynamics corrections theoretical results are confronted with experimental values at the 10-4 cm-1 precision level.
