The results of an investigation of photochemical aerosol formation by 1-hexene, 1,7-octadiene, cyclohexene, cyclopentene, and toluene are reported. The experiments were conducted in the University of North Carolina (UNC) outdoor aerosol chamber utilizing natural sunlight to activate the photochemical reactions in systems containing a single hydrocarbon, nitric oxide (NO), and nitrogen oxide (NO2). The effect of sulfur dioxide (SO2) on these systems was also determined. The chamber was operated as a batch chemical reactor with injections of the reactants made before sunrise, and the chemical and physical transformations were measured until approximately 1500 EDT. Initial conditions were selected to insure photochemical aerosol formation. This program is the first time aerosol formation from these compounds has been investigated under ambient conditions of temperature and solar radiation. The aerosol formation behavior of single hydrocarbons and mixtures with SO2 was investigated with instrumentation yielding size distribution formation.
