Cover Feature: Effects of Microhydration on the Mechanisms of Hydrolysis and Cl− Substitution in Reactions of N2O5 and Seawater (ChemPhysChem 5/2023)

Abstract

The Cover Feature shows the nighttime reactions of dinitrogen pentoxide (N2O5) with chloride (Cl−) and water at the surface of sea spray aerosols. In this work we identify 3 reaction mechanisms in the competition between Cl− substitution and hydrolysis of N2O5 via quantum chemical and dynamics studies of model clusters. The competition of these reactions at aerosol interfaces significantly affects atmospheric levels of O3, NOx, and OH. Cover design by Jami Butler.
