Abstract
We calculate expressions for the quadrupole moments of nonstrange baryons in which the number of QCD color charges is Nc. Using only the assumption of single-photon exchange, we obtain 4 relations among the 6 moments, and show how all of them may be obtained from QΔ+p up to O(1/Nc2) corrections. We compare to the Nc=3 case, and obtain relations between the neutron charge radius and quadrupole moments. We also discuss prospects for the measurement of these moments.
