Abstract
We perform an expansion of the virtual Compton scattering amplitude fo r low energies and low momenta and show that this expansion covers the transition from the regime to be-investigated in the scheduled photon electroproduction experiments to the real Compton scattering regime. We discuss the relation of the generalized polarizabilities of virtual Compton scattering to the polarizabilities of real Compton scattering .
