A study of the polarized structure function of the nucleon is presented. Relativistic corrections have been calculated for the real photon case, corresponding to the Drell-Hearn-Gerasimov sum rule. These corrections have the form of an electric dipole operator, leading to additional absorption strength when the hyperfine interaction is considered. In the case of exchange of virtual photons, a phenomenological expression for the electromagnetic current is derived assuming a sort of impulse approximation for the electron scattering on the single quark. The expected asymptotic behaviour at high momentum transfer is reproduced.
