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

- 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):
- 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)
