Perpendicular paramagnetic bond

A perpendicular paramagnetic bond is a type of chemical bond (in contrast to covalent or ionic bonds) that does not exist under normal, atmospheric conditions.[1] Such a phenomenon was first hypothesized through simulation to exist in the atmospheres of white dwarf stars[2] whose magnetic fields, on the order of 105 teslas,[1] 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.[2]
