Abstract
Ab initio calculations of the magnetic susceptibility and the nuclear magnetic shielding tensor for the SF6 molecule are reported here. Thei r dependence on the choice of gauge for the vector potential, which de scribes the external magnetic field, is discussed. The required invari ance of molecular magnetic properties depends on the fulfillment of ve ry general gauge-invariance sum rules and on the quality of the basis set employed.
