Characterizing highly oxygenated organic molecules in limonene secondary organic aerosols: roles of temperature and relative humidity
Different temperatures and relative humidity levels could alter the chemical composition and product distribution of highly oxygenated organic molecules and secondary organic aerosols during the ozonolysis process.
Paper
Investigation of organic hydrotrioxide (ROOOH) formation from RO2 + OH reactions and their atmospheric impact using a chemical transport model, STOCHEM-CRI
ROOOH formed from the oxidation of RO2 by OH in the troposphere play a significant role in SOA formation.
Paper
Enhanced detection of aromatic oxidation products using NO3− chemical ionization mass spectrometry with limited nitric acid
With limited concentration of reagent nitric acid (HNO3) in the nitrate ion-based chemical ionization mass spectrometry (NO3−-CIMS) we observed increased sensitivity towards many of the aromatic oxidation products.
Paper
Towards automated inclusion of autoxidation chemistry in models: from precursors to atmospheric implications
Demonstration of a novel framework producing autoxidation chemistry reaction schemes: an exemplary application for benzene.
Paper
Interactions of peroxy radicals from monoterpene and isoprene oxidation simulated in the radical volatility basis set
Isoprene affects new particle formation rates in environments and experiments also containing monoterpenes.
Paper
Lifetimes of pre-reactive complexes of peroxy radicals revisited: thermostat effects, temperature dependence and highly oxygenated molecules
Simulated pre-reactive complex lifetime is proportional to experimental measurements of the reactivity of peroxy radicals. This extends to measurements over a range of temperatures.
About this collection
Atmospheric peroxy radicals play a significant role in the formation and degradation of air pollutants. Understanding the chemistry and behaviour of peroxy radicals can help improve air quality models, leading to more accurate predictions of pollution levels and their impacts on human health and the environment. Additionally, peroxy radicals are key intermediates in atmospheric oxidation processes, influencing the atmospheric lifetime of greenhouse gases and contributing to climate change dynamics. This collection highlights the latest impactful research on atmospheric peroxy radical chemistry.
