The strength of multipole radiation most commonly decreases in the following order: (1) electric dipole, (2) electric quadrupole, magnetic dipole, (3) electric octupole, magnetic quadrupole, etc. An exception is rotational transitions of the O₂ molecule, which has stronger magnetic dipole radiation (due to its unpaired electrons) than electric dipole (since it is a symmetric, homonuclear molecule).; 0
