The second negative band system of O{sub 2}{sup +} arises from the transition A{sup 2}II{sub u}({nu}{prime}) {yields} X{sup 2}II{sub g}({nu}{double prime}). The excited electronic state A{sup 2}II{sub u} can be populated by photoionization and electron impact ionization of O{sub 2} and by fluorescent scattering of radiation by O{sub 2}{sup +} (X{sup 2}II{sub g}) in planetary and cometary atmospheres. Transition probabilities for the second negative band system of O{sub 2}{sup +} are computed using the dipole transition moment presented by Wetmore et al. (1984). Vibrational levels {nu}{double prime} = 0-54 of the X{sup 2}II{sub g} ground state and {nu}{prime} = 0-33 of the excited A{sup 2}II{sub u} state are included. Franck-Condon factors for ionization-excitation of O{sub 2} (X{sup 3}{Sigma}{sub g}{sup {minus}}; {nu} = 0-25) to O{sub 2}{sup +}(A{sup 2}II{sub u}; {nu}{prime} = 0-33) are also presented.
