N2 - The paper contains a systematic, model-independent treatment of electric dipole (E1) transitions in heavy quarkonium. Within the effective field theory framework of potential nonrelativistic QCD, we derive the complete set of relativistic corrections of relative order v2 both for weakly and strongly coupled quarkonia. The result supports and complements former results from potential model calculations.
