abstract = {The chemical kinetics of organic nitrate production during
new particle formation and growth of secondary organic
aerosols (SOA) were investigated using the short-lived
radioactive tracer 13N in flow-reactor studies of α-pinene
oxidation with ozone. Direct and quantitative measurements
of the nitrogen content indicate that organic nitrates
accounted for $∼40\%$ of SOA mass during initial particle
formation, decreasing to $∼15\%$ upon particle growth to
the accumulation-mode size range (>100 nm). Experiments with
OH scavengers and kinetic model results suggest that organic
peroxy radicals formed by α-pinene reacting with secondary
OH from ozonolysis are key intermediates in the organic
nitrate formation process. The direct reaction of α-pinene
with NO3 was found to be less important for particle-phase
organic nitrate formation. The nitrogen content of SOA
particles decreased slightly upon increase of relative
humidity up to $80\%.$ The experiments show a tight
correlation between organic nitrate content and SOA
particle-number concentrations, implying that the condensing
organic nitrates are among the extremely low volatility
organic compounds (ELVOC) that may play an important role in
the nucleation and growth of atmospheric nanoparticles.},
