The gas-phase products of the reaction between aqueous HNO3 and NaCl were identified and quantified using IR and UV-Vis spectroscopy. Utilizing a multicomponent Beer’s law analysis incorporating single wavelength UV-Vis absorption cross-sections and integrated IR absorption cross-sections from the primary literature, the major products of the reaction were determined to be Cl2 and ClNO. Other quantified products were NO2, HCl, ClNO2 and N2O. The product distribution of the reaction is highly dependent on chloride ion and HNO3 concentration and mechanistic implications are proposed. As photolyzable chlorine-containing gases are players in the oxidation chemistry of the polluted troposphere, the potential atmospheric significance of the results is discussed.
