Abstract

For a magnetically anisotropic lanthanide complex the pseudo-contact contributions to the induced shift may, under certain definable conditions for internal rotations, still be proportional to an expression of the type (3 cos2θ– 1)γ–3 even when the susceptibility tensor is not axially symmetric.
