UHk SCF ulculations with ZI medium-sized basis set of gaussian lobe functions have been performed on the ground state of the X0 Ladical. All the harmonic and the diagonal cubic force constants have been calculated by thb force method of Pulay. From the force constants, vibrational frequexies have been calculated by Wikon's FG method. The geometry of HCO in its ,gdund state and fust excited state ha& been calculated by the force relaxation method.

A case of appearance of multiple unrestricted Hartree-Fock (UHF) solutions in the SNH' (2A') radical is reported. This kind of solution does not arise from different electron configurations or symmetry breaking efiects and seem to be exclusive of the UHF method. Three solutions are found and studied
Expressions for the diamagnetic part of the Cotton-Mouton constant and the hyperpolarizability of helium are obtained within the coupled Hartree-Fock approximation; they involve solutions of integro-differential equations which are solved numerically in a calculation of these properties. An earlier
