NICS is a local measure of the strength of the magnetically induced currents. It is negative (shielding) around the inner rim of aromatic rings like benzene and positive (deshielding) around their periphery because of the diamagnetic ring currents. The shielding/deshielding regions reverse in the case of antiaromatic rings because of the paramagnetic ring currents. Many TMs, lanthanides, and actinide atoms sustain strong local paramagnetic currents akin to the antiaromatic rings; therefore, their neighboring atoms (or ghost atoms that are probes of NICS computation) are strongly influenced depending on where they lie on the shielding/deshielding regions of the paramagnetic local currents. In a cyclic structure containing several TMs the center of the ring experiences a strong shielding because of the local paramagnetic current around the metal atoms. This shielding effect disappears a few angstroms above/below the ring plane and replaces with deshielding arising from the local paramagnetic current cones around the atoms, Figure .
