Ozone

 * Ozone-oxygen cycle (Chapman mechanism):
 * O2 + hν → 2O
 * O + O2 + M → O3 + M
 * O3 + hν → O2 + O (highly exothermic)
 * O + O3 → 2O2

 * Dobson unit
 * Photochemical smog
 * Tropospheric ozone depletion events
 * Polar vortex, Polar night
 * Polar stratospheric clouds (PSCs)
 * Chlorine is reactivated on PSCs: J. Phys. Chem. (1995) 99, 6258–6262
 * Ozone depletion potential (O3 is ozone, CFCl3 is trichlorofluoromethane):
 * $${\text{ODP(X)}} = \frac$$


 * Hydroxyl radical, HO2 radical:
 * Oxidation of hydrocarbons and carbon monoxide by ozone, catalysed by the OH radical, normally keeps tropospheric ozone very low:
 * CO + OH → CO2 + H
 * H + O2 + M → HO2 + M
 * HO2 + O3 → OH + 2O2
 * CO + O3 → CO2 + O2 (net)
