In this subsection, we outline the methods for determining the χ s tensor as expressed in eq. 1, which, as previously mentioned, represents the magnetic susceptibility formulation of the general equation (eq. . Given that we have already presented the general equation in terms of magnetic susceptibility, denoted as χ s , we will discuss all aspects exclusively within this magnetic susceptibility framework. By this, we aim to establish a seamless connection between the evaluation of the paramagnetic shielding tensor and the preceding developments outlined in this discussion.
