    "abstract": "We are studying the electron scattering process e p to e\u0027 p\u0027 gamma in order\nto obtain information on the genuine virtual Compton scattering (VCS) process\ngamma^* N to gamma N. In addition to the two kinematical variables of real\nCompton scattering, e.g. the scattering angle theta and the energy omega\u0027 of\nthe outgoing photon, the invariant amplitude for VCS depends on a third\nkinematical variable, which we choose as the absolute value of the\nthree-momentum transfer to the nucleon. The structure-dependent coefficients in\nthe VCS amplitude therefore acquire a momentum dependence and are termed\n``generalized polarizabilities\u0027\u0027 of the nucleon in analogy to real Compton\nscattering. Utilizing the heavy baryon formalism of chiral perturbation theory\nwe present predictions for the momentum dependence of the ``generalized\npolarizabilities\u0027\u0027 and discuss the VCS response functions to be measured in the\nscheduled electron scattering experiments.",
