Figure 9
Variation in bond order as a function of O–O distance in the dioxygenyl cation (O2)+, dioxygen (O2)0, superoxide (O2)− and peroxide (O2)2−. The line is fit to the data and extrapolated to a distance of 3 Å for zero bond order; the value of 3 Å is somewhat speculative, but the resulting curve is not very sensitive to small changes in this value. |
