Preferred Label : spin polarization;
IUPAC definition : Static and dynamic spin polarization effects are distinguished. The static polarization
of an electron spin occurs in the C–H bonds of aromatic radicals where the σ-electron
closest to an unpaired π-electron tends to have its spin parallel to that of the π-electron.
Likewise, static spin polarization arises in the π-system of conjugated radicals:
the electron of the doubly occupied molecular orbital prefers to take a closer spatial
position to the odd one, which spin is parallel to the latter. The effect reflects
the energy unfavourable situation if an electron of opposite spin were to come nearby.;
