## Abstract It is shown that gauge terms can be introduced into the Gaussian functions used as the basis functions for an __ab initio__ calculation of the energy of a molecule in the presence of a uniform magnetic field so that all the integrals become independent of the origin of the vector potent

Abstract
The magnetic susceptibility and screening constant tensors are calculated using an ab initio finite perturbation SCF method, with gauge invariant Gaussian orbitals. The isoelectronic BH BeH^โ^, and CH^+^ molecules have been studied. The calculated values for BH are relatively different from those obtained by other methods. The CH^+^ molecule seems to exhibit a stronger temperature independent paramagnetism than BH, while the BeH^โ^ molecule would be diamagnetic. The screening constants of the heavy atom of these molecules present a similar variation.
