Virtual Compton Scattering (VCS) on the proton has been studied at Jefferson Lab using the exclusive photon electroproduction reaction ep → epγ. This paper gives a detailed account of the analysis which has led to the determination of the structure functions PLL − PT T /ǫ and PLT , and the electric and magnetic generalized polarizabilities (GPs) αE(Q 2 ) and βM (Q 2 ) at values of the four-momentum transfer squared Q 2 = 0.92 and 1.76 GeV 2 . These data, together with the results of VCS experiments at lower momenta, help building a coherent picture of the electric and magnetic GPs of the proton over the full measured Q 2 -range, and point to their non-trivial behavior.

Exclusive electroproduction of 0 mesons on protons in the backward hemisphere has been studied at Q 2 = 1.0 GeV 2 by detecting protons in the forward direction in coincidence with scattered electrons from the 4 GeV electron beam in Jefferson Lab's Hall A. The data span the range of the total ͑␥ * p͒ center-of-mass energy W from the pion production threshold to W = 2.0 GeV. The differential cross sections T + ⑀ L , TL , and TT were separated from the azimuthal distribution and are presented together with the MAID and SAID parametrizations.
