Analyses of data from the inelastic scattering of 65 MeV protons and of 57 to 215 MeV electrons are used to test large basis (projected Hartree-Fock) model spectroscopies for the ground to $2_1^{+}$ (4.43 MeV) transition in ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$. From distorted wave approximation calculations of the proton scattering, reasonably good agreement with the empirical cross section was obtained, but no spectroscopy yields the distinctive structure of the recently measured analyzing power data. In like fashion, the longitudinal form factor extracted from the electron scattering data is well reproduced by calculations based upon the same projected Hartree-Fock models of spectroscopy. The predictions of the transverse form factor, however, are quite distinctive and only in one case, and that involving a strong spin orbit effect in the basis, are the data reproduced.
