Webbtheory, on the other hand, there is a non-zero diamagnetic effect, as was first shown by Landau (1930). The new features introduced by the quantum theory are twofold. First, the energy states of an electron in the presence of a magnetic field are not the same as the energy states in the absence of a field, and one may say that the radii WebbO₂ is a diradical. The reaction when oxygen binds to hemoglobin is. Fe²⁺ + O₂ → Fe³⁺ + O₂·⁻ (Fe is oxidized; O₂ is reduced) The O₂·⁻ still has one unpaired electron. When low-spin Fe³⁺ binds to O₂·⁻, the spins of the two unpaired electrons couple strongly. (S = ½ - ½ = 0), so oxyhemoglobin is diamagnetic.
WebbDiamagnetism is the phenomenon of a magnetic field inducing in a material a magnetic field which opposes it. In other words, a diamagnetic material has a negative magnetic susceptibility. The diamagnetic susceptibilities are very small in magnitude compared to paramagnetic materials, and negligible compared to ferromagnetic materials.

Webb1 jan. 2009 · Diamagnetism is a property displayed by all materials and is explained semiclassically as an induction effect (χ < 0). With the help of Bohr–van Leeuwen theorem, it is possible, however, to prove that magnetism in any form, that means, including diamagnetism, is a pure quantum mechanical phenomenon.
