Short summary
Condensed-phase reactions are important removal processes for reduced nitrogen species, isocyanic acid (HNCO), methyl isocyanate (CH3NCO), and cyanogen halides (XCN, X = Cl, Br, I). This chemistry is not well understood, so we measured aqueous-phase solubilities and reaction rates under a range of temperatures and conditions and in n-octanol, a proxy for non-polar media and biological membranes. The results were used to estimate atmospheric removal rates and fates of these nitrogen compounds.
