    "abstract": "We investigate the spin-independent part of the virtual Compton scattering\n(VCS) amplitude off the nucleon within the framework of chiral perturbation\ntheory. We perform a consistent calculation to third order in external momenta\naccording to Weinberg\u0027s power counting. With this calculation we can determine\nthe second- and fourth-order structure-dependent coefficients of the general\nlow-energy expansion of the spin-averaged VCS amplitude based on gauge\ninvariance, crossing symmetry and the discrete symmetries. We discuss the\nkinematical regime to which our calculation can be applied and compare our\nexpansion with the multipole expansion by Guichon, Liu and Thomas. We establish\nthe connection of our calculation with the generalized polarizabilities of the\nnucleon where it is possible.",
