The third-order nonlinear optical susceptiblity chi(3) of a C60 molecule is calculated by using a free-electron model as well as by taking Coulomb interactions into account. The free-electron model yields chi(3) magnitudes which are in agreement with experiment. Althugh Coulomb interactions reduce chi(3) by one order of magnitude, local-field corrections can be invoked to recover the agreement.
