Preferred Label : configuration (electronic);
IUPAC definition : A distribution of the electrons of an atom or a molecular entity over a set of one-electron
wavefunctions called orbitals, according to the Pauli principle. From one configuration
several states with different multiplicities may result. For example, the ground electronic
configuration of the oxygen molecule (O sub 2 /sub ) is: 1σg2, 1σu2, 2σg2, 2σu2, 1πu4,
3σg2, 1πg2 resulting in the 3Σg , Δg1 and Σg 1 multiplets.;
