[PAR] [TLE] Leighton relationship [SEP] In atmospheric chemistry, the Leighton relationship is an equation that determines the concentration of tropospheric ozone in areas polluted by the presence of nitrogen oxides.  Ozone in the troposphere is primarily produced through the photolysis of nitrogen dioxide at wavelengths (λ) less than 430 nm, which are able to reach the lowest levels of the atmosphere, through the following mechanism: [PAR] [TLE] Ozone [SEP] Ozone (systematically named 1λ,3λ-trioxidane and "catena"-trioxygen), or trioxygen, is an inorganic molecule with the chemical formula O3 .  It is a pale blue gas with a distinctively pungent smell.  It is an allotrope of oxygen that is much less stable than the diatomic allotrope O2 , breaking down in the lower atmosphere to O2 or dioxygen.  Ozone is formed from dioxygen by the action of ultraviolet light and also atmospheric electrical discharges, and is present in very low concentrations throughout the Earth's atmosphere (stratosphere).  Its concentration is highest in the ozone layer region of the atmosphere, which absorbs most of the Sun's ultraviolet (UV) radiation.
