The Gerasimov-Drell-Hearn sum rule relates the helicity dependent total photo-absorption cross section of circularly polarized photons on polarized nucleons to the nucleon anomalous magnetic moment. This sum rule follows from unsubtracted dispersion relation applied to the forward Compton-scattering amplitude and the Low Energy Theorem. Because of the 1/? weight, the sum rule is mostly sensitive to the low energy part of the cross section.
