Novel synthetic methods to produce β,γ, and σ-hydroxy nitrates, which are formed via the atmospheric reaction of alkanes and alkenes, were developed using NMR and IR spectroscopies. Henry's law coefficients of C4 and C5 hydroxy nitrates at 291 ± 2 K were measured using a dynamic equilibrium system. The solubility decreased with the organic chain length and increased with increasing distance between the nitrooxy and hydroxy groups. These species divided into droplets in the presence of clouds and fogs. Appropriate parameters of hydroxy nitrates photochemical reactions, such as rate coefficients, absorption cross sections, and quantum yields were necessary to determine the atmospheric lifetime of the species. The estimated lifetime (> 2 days) implied that hydroxy nitrates are important NOx reservoir species and can survive long range transport in the troposphere, especially in dry environments.
