Peroxyacyl nitrates contain two relatively weak bonds that can be broken by low-energy photons. The weakest is the N−ON−O bond in the nitrate functional group of the molecule with a standard bond-dissociation energy of 201 kJ mol−1. What is the longest wavelength of a photon, in nanometres, that has enough energy to cause the photodissociation of the weakest bond. Assume all energy of the photon is efficiently used for the photodissociation
One of the highest concentrations of peroxyacyl nitrates has been found in the Los Angeles (LA) basin at 30 ppbppb, reaching its peak at mid-afternoon. Most of the pollution in the LA basin is created in an area of only 3000 km2km2 and the pollution depth below the inversion layer is normally about 500 mm. This concentration was therefore found in 1500 km3km3 of air above Los Angeles.
