Abstract

N$_{2}$O$_{5}$ is an atmospheric species which serves as night-time sink for NO$_{x}$ species. Its reconversion to NO$_{x}$ products occurs through solvation in atmospheric aerosols. Detection of N$_{2}$O$_{5}$ and NO$_{3}$$^{-}$ fragmentation products in such aerosols has previously utilized chemical ionization featuring halides (of which chlorine is ubiquitous in sea-spray aerosols). We examine the solvation behavior of N$_{2}$O$_{5}$ and the critical number of water molecules to form HNO$_{3}$ from N$_{2}$O$_{5}$ and water. We have been able to generate and spectroscopically characterize N$_{2}$O$_{5}$-halide ions formed from halide-water clusters. We observe X$^{-}$N$_{2}$O$_{5}$ species whose spectra best correspond to a calculated (O$_{2}$NX)(ONO$_{2}$$^{-}$) species.footnote{Funding for this work was provided by the NSF’s Center for Aerosol Impacts on Climate and the Environment.}
