The Hartree–Fock magnetizability of C60

Using London atomic orbitals and a recent parallel implementation of our second-order ab initio property code, we have determined the Hartree–Fock limit for the magnetizability of C60 to be −359±5 ppm cgs, in excellent agreement with earlier basis-set limit extrapolations. Using diamagnetic exaltation as a criterion for aromaticity, our calculations show that C60 is an aromatic molecule with a relative diamagnetic exaltation greater than that of benzene.
