Fast photolysis of carbonyl nitrates from isoprene
Photolysis is shown to be a major sink for isoprene-derived carbonyl nitrates, which constitute an important component of the total organic nitrate pool over vegetated areas. Empirical evidence from published laboratory studies on the absorption cross sections and photolysis rates of α-nitrooxy ketones suggests that the presence of the nitrate group (i) greatly enhances the absorption cross sec...
متن کاملDirect photolysis of carbonyl compounds dissolved in cloud and fog droplets
Gas-phase photolysis is an important tropospheric sink for many carbonyl compounds; however the significance of direct photolysis of these compounds dissolved in cloud and fog droplets is uncertain. We develop a theoretical approach to assess the importance of aqueous photolysis for a series of carbonyls that possess carboxyl and hydroxyl functional groups by comparison with rates of other atmo...
متن کاملDetermination of Photolysis Frequencies and Quantum Yields for Small Carbonyl Compounds using the EUPHORE Chamber
Small aldehydes are formed during the photochemical oxidation of many VOC’s, olefins and terpenes in urban as well as in rural areas. Photolysis and reaction with the OH radical are the most important initiation reactions for the removal of these compounds conducting to the formation of peroxy radicals and in the case of photolytic decomposition, either to stable molecules or free radicals. The...
متن کاملAnalysis of aliphatic and aromatic carbonyl compounds in ambient air by LC/MS/MS.
A sensitive liquid chromatograph/tandem mass spectrometric technique (LC/MS/MS) was applied to determine aliphatic and aromatic carbonyl compounds in ambient air. Traces of the carbonyl compounds were sampled by passing through a Sep-Pak DNPH-silica cartridge. Their derivatives were thus eluted with acetonitrile, separated by reversed-phase liquid chromatography and determined by quadrupole tan...
