Preferred Label : Pauli exclusion principle;
IUPAC definition : A rule, complementary to the aufbau principle, of building up the electronic configuration
of atoms and molecules: a maximum of two electrons can occupy an orbital and then
only providing that the spins of the electrons are paired, i.e. opposed. The principle
demands that the wavefunction for a many-electron system must be asymmetric with respect
to the permutation of the space-spin coordinates for every pair of electrons.;
Scope note : antisymmetry principle.;
