aElectronic configurations are not shown for those atoms/molecules at their ground states. Units are s-1 for photolysis reactions, cm3 s-1 for two-body reactions, and cm6 cm-1 for three-body reactions. The photolysis rate coefficients are given at the top of the model atmosphere. Note that O = 16O, P = 17O, and Q = 18O. (R83)-(R87) denote a net loss of ozone by catalysis (see text for details).
