S2 Reactions of NO with Ions in Water: Microscopic Mechanisms, Intermediates, and Products.

Reactions of dinitrogen pentoxide (NO) greatly affect the concentrations of NO, ozone, OH radicals, methane, and more. In this work, we employ ab initio molecular dynamics and other tools of computational chemistry to explore reactions of NO with anions hydrated by 12 water molecules to shed light on this important class of reactions. The ions investigated are Cl, SO, ClO, and RCOO (R = H, CH, CH).

Reactions of NO with Salty and Surfactant-Coated Glycerol: Interfacial Conversion of Br to Br Mediated by Alkylammonium Cations.

Gas-liquid scattering and product-yield experiments are used to investigate reactions of NO with glycerol containing Br and surfactant ions. NO oxidizes Br to Br for every solution tested: 2.7 M NaBr, 0.

Aromatic organosulfates in atmospheric aerosols: synthesis, characterization, and abundance.

Aromatic organosulfates are identified and quantified in fine particulate matter (PM) from Lahore, Pakistan, Godavari, Nepal, and Pasadena, California. To support detection and quantification, authentic standards of phenyl sulfate, benzyl sulfate, 3-and 4-methylphenyl sulfate and 2-, 3-, and 4-methylbenzyl sulfate were synthesized. Authentic standards and aerosol samples were analyzed by ultra-performance liquid chromatography (UPLC) coupled to negative electrospray ionization (ESI) quadrupole time-of-flight (ToF) mass spectrometry.
