The energy-weighted sum rule for an electric dipole transition operator of a Schiff type differs from the Thomas–Reiche–Kuhn (TRK) sum rule by several corrective terms which depend on the number of system components, [Formula: see text]. For illustration the formalism was applied to the case of Na clusters. One concludes that the random phase approximation (RPA) results for Na clusters obey the modified TRK sum rule.
