Fig. 7.26 Streamlines and modulus of the current density vector field induced in cubane by a
magnetic field B z with magnitude 1 au normal to a face of the cube and directed outward, plotted
(left) in the xy plane through the centre of the molecule; (right) in the plane of a face. The projection
of atom positions is marked by a cross. The maximum modulus (step between two consecutive
contours) in au is 4:8 Â 10
À2 (4 Â 10
À3 ) on the left, 1.93, cut at 0.2, (2 Â 10
À2 ) on the right
