Secondary organic aerosol and organic nitrogen yields from the nitrate radical (NO3) oxidation of alpha-pinene from various RO2 fates

Kelvin H. Bates et al.

Summary: The reaction of alpha-pinene with NO3 is important for the removal of alpha-pinene and NO3 at night, and it may have significant implications for secondary organic aerosol (SOA) and reactive nitrogen in the atmosphere.

Synthesis and Hydrolysis of Atmospherically Relevant Monoterpene-Derived Organic Nitrates

Yuchen Wang et al.

Summary: The study synthesized seven monoterpene-derived ONs and investigated their hydrolysis in bulk solutions at different pH values. The results showed that the hydrolysis lifetimes were related to alkyl substitution numbers, functional groups, and carbon skeletons. Tertiary and secondary ONs hydrolyzed via an acid-catalyzed unimolecular mechanism, while primary ONs showed a competition of unimolecular and bimolecular mechanisms.

Gas- and Particle-Phase Products and Their Mechanisms of Formation from the Reaction of Δ-3-Carene with NO3 Radicals

Marla P. DeVault et al.

Summary: Monoterpenes are a major source of biogenic volatile organic compounds emitted into the atmosphere annually. A study on the reaction of Delta-3-carene with NO3 radicals revealed the formation of first-generation ring-retaining and ring-opened compounds in the gas phase, while the particle phase consisted mainly of oligomers composed of acetal and hemiacetal dimers. These findings highlight the impact of monoterpene structure on the formation of multifunctional products and significant amounts of secondary organic aerosol.

Minimizing Errors in Measured Yields of Particle-Phase Products Formed in Environmental Chamber Reactions: Revisiting the Yields of β-Hydroxynitrates Formed from 1-Alkene + OH/NOx Reactions

Julia G. Bakker-Arkema et al.

Summary: Environmental chamber studies are essential for measuring reaction product yields and secondary organic aerosols formed from the oxidation of volatile organic compounds to develop atmospheric chemistry models. These measurements are challenging due to various potential sources of errors that need careful consideration and mitigation.

Comparison of methods of functional group analysis using results from laboratory and field aerosol measurements

Megan S. Claflin et al.

Summary: A study comparing two methods for analyzing functional groups in SOA found that both FTIR spectroscopy and derivatization-spectrophotometric methods are adequate for measuring the functional group composition of SOA. While the derivitization-spectrophotometric methods offer more specificity, they also require more time and aerosol mass for sample analysis than the FTIR methods. Functional group signatures obtained from SOA generated in environmental chambers can potentially be used to gain insight into oxidation and particle-phase reactions responsible for SOA formation in field samples.

Comprehensive Analysis of Products and the Development of a Quantitative Mechanism for the OH Radical-Initiated Oxidation of 1-Alkenes in the Presence of NOx

Julia G. Bakker-Arkema et al.

Summary: The reactions of 1-tetradecene and 1-pentadecene with OH radicals in the presence of NOx were investigated in environmental chamber experiments. The measured molar yields of products formed were used to calculate branching ratios and to achieve a complete gas-phase reaction mechanism for 1-alkenes.

Photolytically induced changes in composition and volatility of biogenic secondary organic aerosol from nitrate radical oxidation during night-to-day transition

Cheng Wu et al.

Summary: Night-time reactions of biogenic volatile organic compounds (BVOCs) and nitrate radicals (NO3) can lead to the formation of NO3-initiated biogenic secondary organic aerosol (BSOANO(3)). Light exposure has significant impacts on the chemical composition and volatility of BSOANO(3), indicating substantial changes during photolytic ageing.

Experimental and theoretical study on the impact of a nitrate group on the chemistry of alkoxy radicals

A. Novelli et al.

Summary: A study combining theoretical and experimental methods examined the chemistry of nitrated alkoxy radicals and their impact on RO2 measurements using the LIF technique. Results showed slower decomposition rates for beta-nitrate-alkoxy radicals compared to beta-OH-substituted alkoxy radicals, with implications for RO2 measurements in both ambient and experimental conditions. Experimental results confirmed the dominant role of NO3 radicals in alkene oxidation and the formation of HO2 and RO2 radicals, aligning with earlier literature data.

Measurements of the partitioning of nitric acid and sulfuric acid in aqueous/organic phase-separated systems

Benjamin L. Deming et al.

Summary: The partitioning of sulfuric acid and nitric acid between aqueous and organic phases may play a role in acid catalysis of organic reactions, depending on the O:C ratio and water content of the organic phase. The addition of ammonium sulfate can lead to an increase or decrease in the partitioning of sulfuric acid to the organic phase, depending on the balance of HSO4- concentration and water content of the organic phase.
