Current density maps on the plane of the ring (left), at 0.5a₀ (center), and at 1.0a₀ distance (in bohr) from the plane of the ring. The current densities are represented by streamlines; the magnitudes of the current density are indicated by a decreasing scale: white-yellow-black. The external magnetic field vector points toward the reader. The integration plane is perpendicular to the molecular plane and is indicated by a cyan line, labeled with the calculated net ring current strength (RCS) in nA T⁻¹.
