Visualization of the current density maps (or flow) to analyze aromaticity. This visualization is realized using both two-dimensional and three-dimensional stream- line plots. The clockwise (diatropic) and counterclockwise (paratropic) direction of the current flow indicates aromaticity or antiaromaticy, respectively. Top: Current density maps (C at the molecular plane and at 1a₀ (1 bohr) distance from the plane of the benzene ring). The current flow is represented by streamlines; the magnitudes of the currents are indicated by a decreasing scale: white-yellow-red-black. Middle and bottom: Two orientations of the three-dimensional current density vector field.
