    experiment_summary: "Experiments were conducted in an 8.0 m3 FEP Teflon environmental\r\nchamber in Boulder, CO, that was filled with clean, dry air [<5\r\nppb of hydrocarbons and <1% relative humidity (RH)] from\r\ntwo Aadco clean air systems and operated at ambient\r\ntemperature (?23 °C) and pressure (?630 Torr). The VOC was\r\nadded to the chamber by evaporating a measured amount of\r\nthe compound from a heated glass bulb into a stream of\r\nultrahigh-purity (UHP) N2. Approximately 200 ?g m?3 dioctyl\r\nsebacate (DOS) seed particles in UHP N2 were added from an\r\nevaporation?condensation apparatus. Known amounts of\r\nmethyl nitrite and NO were prepared on a vacuum manifold\r\nusing a calibrated glass bulb and absolute pressure gauge and\r\nthen flushed into the chamber with UHP N2. Reactions were\r\ninitiated by turning on blacklights that covered two walls of the\r\nchamber at 50% intensity (JNO2 = 0.37 h?1) for one hour. Photolysis of methyl nitrite created OH radicals with an average concentration of 4 × 107 molecules cm?3, as determined from the measured decay\r\nof the VOC and estimated OH reaction rate constants. The\r\nVOC, methyl nitrite, and NO concentrations were 1, 5, and 5\r\nppm."
