The large anisotropy of diamagnetic susceptibility of benzene, which is considered to be due to the free migration of π-electrons, is investigated by the antisymmetrized LCAOMO method.We have included all the cofigurations obtained by excitation of one or two electrons from the lowest configuration, and we have retained all manycenter-integrals.The calculated value of diamagnetic anisotropy is about 50% of the experimental value.The effect of configuration interaction was found to be rather small.
