Dioxygen-related species and hydrogen peroxide

The oxygenyl cation, O, is well characterized in both the gas phase and in salts with non-oxidizable anions. Removal of one of the antibonding electrons from O2 gives O with a bond order of 2.5 and, consequently, a shorter bond length of 112.3 pm. The chemistry of Ot is quite limited in scope because of the high ionization potential of O2 (1163 kJ mol-1). 

The superoxide ion O-f is formed by adding one electron into the antibonding orbital of O2, thereby reducing the bond order to 1.5 and increasing the bond
