Perpendicular paramagnetic bond explained

A perpendicular paramagnetic bond is a type of chemical bond that does not exist under normal, atmospheric conditions. Such a phenomenon was first hypothesized through simulation to exist in the atmospheres of white dwarf stars[1] whose magnetic fields, on the order of 105 teslas,[2] could allow such interactions to exist. In a very strong magnetic field, excited electrons in molecules may be stabilized, causing these molecules to abandon their original orientations parallel to the magnetic field and instead lie perpendicular to it.[3] Normally, at such intense temperatures as those near a white dwarf, more common molecular bonds cannot form and existing ones decompose.
