Hydrolysis and gas-particle partitioning of organic nitrates formed from the oxidation of α-pinene in environmental chamber experiments [link]Website  abstract   bibtex   

Gas-particle partitioning and hydrolysis of organic nitrates (ON) influences their role as sinks and sources of NOx and their effects on the formation of tropospheric ozone and organic aerosol (OA). Organic nitrates were formed from the photo-oxidation of α-pinene in environmental chamber experiments under varying conditions. A hydrolysis rate of 2 day−1 was found for particle-phase ONs at a relative humidity of 22 % or higher; no significant ON hydrolysis was observed at lower relative humidity. The ON gas-particle partitioning is dependent on total OA concentration and temperature, consistent with absorptive partitioning theory. In a volatility basis set the ON partitioning is consistent with mass fractions of [0 0.19 0.29 0.52] at saturations mass concentrations (C*) of [1 10 100 1000] μg m−3.
