## Abstract We calculated the second‐order perturbed energy and the first‐order perturbed wave function of the hydrogen molecular ion by the Green function method based on a united atom with effective nuclear charge, __Z__. Since the perturbation is given by (__Z__/__r__) — (1/__r__~A~) — (1/__r__~
