• Resumen

  • The singlet term of dioxygen with one doubly occupied π* orbital has lower energy than the singlet term with two singly occupied π* orbitals even though single occupancy is favored in the aufbau of atoms. A simple physical explanation based on orbital angular momentum explains this double occupancy.
