摘要：

A complete effective Hamiltonian for relativistic corrections at orders m alpha(6) and m alpha(6) (m/M) in a one-electron molecular system is derived from the nonrelativistic QED Lagrangian. It includes spin-independent corrections to the energy levels and spin-spin scalar interactions contributing to the hyperfine splitting, both of which had been studied previously. In addition, corrections to electron spin-orbit and spin-spin tensor interactions are obtained. This allows the improvement of the hyperfine structure theory in hydrogen molecular ions. Improved values of the spin-orbit hyperfine coefficient are calculated for a few transitions of current experimental interest.
