Figure 2
Left: a classical representation of the dipole (vector) moments permitted by a classical orbital. The magnetic moment [{\boldmu}] points out of the page and is perpendicular to the orbital plane. The polar (electric dipole) moment, [{\bf p}], lies parallel to the major orbital axis. The toroidal moment, T, lies perpendicular to the polar and magnetic moments, in the direction of their cross-product, and is thus odd under reversal of either, but even under reversal of both. Right: the slightly counter-intuitive case of zero magnetic moment and parallel polar and toroidal moments can be visualized classically as the superposition of two rotated and reflected orbitals, forming a `butterfly' pattern.
