The electron density arising from the highest occupied orbital in the triplet state of lithium hydride. The lowest triplet state is unbound at zero field, but becomes bound in a sufficiently strong perpendicular magnetic field. The density is illustrated by isosurfaces, viewed at two different angles (left and right). A perpendicular magnetic field of 0.2 au (or 47,000 tesla) results in the red isosurface and a field of 0.6 au (or 141,000 tesla) results in the green isosurface. A field 0.2 au is not strong enough to make the system bound and the red isosurface corresponds to an sp hybrid orbital. In a stronger field of 0.6 au, the triplet state becomes paramagnetically bound as Li p-1 orbital is mixed into the highest occupied orbital.
Left: Streamlines and isosurfaces for the current density in a benzene molecule subject to a strong, uniform magnetic field, directed out of the molecular plane. Black dots mark the positions of the carbon and hydrogen atoms. Right: Streamlines and isosurfaces for a benzene molecule in a strong, non-uniform magnetic field, with a constant curl directed out of the molecular plane.
More examples will be added soon.
