The authors' previous calculations of pairing energies for dn configurations are extended to fn configurations. The ground state of f2, as in PuF6, is shown to be nondegenerate whether the spins are paired or not. However, detailed calculations show the magnetic properties to favor the view that the spins are in fact paired. This assumption is also found to accord with the observed variation of vibrational frequencies for UF6, NpF6, and PuF6.
