Abstract

The far ultraviolet absorption spectrum of oxygen has been photographed under high dispersion in the region 1300-650A. The bands are explained as going to the various excited states of $O_{2}^{+}$ as limits and are attributed to the removal of $v π$ , $ω π$ and $x σ$ electrons, respectively, from the normal state of $O_{2}$ . The results strongly support Mulliken's assignment of the visible $O_{2}^{+}$ bands to the transition ${}^{4}{Σ_{g}}^{-} \to {}^{4}Π_{u}$ . The distances of the ${}^{4}Π_{u}$ and ${}^{4}{Σ_{g}}^{-}$ states of $O_{2}^{+}$ from the ground state of $O_{2}$ are given as 16.1 and 18.2 volts, respectively, with possible errors of about a tenth of a volt. The appearance and nonappearance of strong electronic series going to known ionization potentials are also discussed.
