Description: Das Projekt "The Formation of Peroxyacetyl Nitrate (PAN) in Summer Smog" wird vom Umweltbundesamt gefördert und von Eidgenössische Anstalt für Wasserversorgung, Abwasserreinigung und Gewässerschutz durchgeführt. Peroxyacetyl nitrate (PAN) is an important component of summer smog. It can cause eye irritation and plant damage. PAN is also a temporary reservoir for reactive intermediates involved in summer smog formation. Therefore it is essential to know the kinetics and mechanism of its formation and destruction for inclusion in models of atmospheric chemistry. PAN is formed as a secondary product following the OH radical initiated photo-oxidation of acetaldehyde, which leads to the generation of peroxyacetyl radicals. Peroxyacetyl radicals may either react with NO2 to generate PAN or with NO to form radical products and CO2. The aims of this project are: (i) to determine the branching ratio between the two reactions, (ii) to determine the rate and mechanism of the thermal decomposition of PAN analogues.
