Abstract
The energy-weighted sum rule for an electric dipole transition operator of a Schiff type differs from the Thomas-Reiche-Kuhn sum rule by several corrective terms which depend on the number of system components, . For illustration the formalism was applied to the case of clusters. One concludes that the RPA results for clusters obey the modified TRK sum rule.
