Reaction Kinetics of Green Leaf Volatiles with Sulfate, Hydroxyl, and Nitrate Radicals in Tropospheric Aqueous Phase.

ABSTRACT: Green plants exposed to abiotic or biotic stress release C-5 and C-6 unsaturated oxygenated hydrocarbons called Green Leaf Volatiles (GLVs). GLVs partition into tropospheric waters and react to form secondary organic aerosol (SOA). We explored the kinetics of aqueous-phase reactions of 1-penten-3-ol (PENTOL), (Z)-2-hexen-1-ol (HEXOL), and (E)-2-hexen-1-al (HEXAL) with SO₄^•-, ^•OH, and NO₃^•. At 298 K, the rate constants for reactions of PENTOL, HEXOL, and HEXAL with SO₄^•- were, respectively, (9.4 ± 1.0) × 10⁸ L mol^-1 s^-1, (2.5 ± 0.3) × 10⁹ L mol^-1 s^-1, and (4.8 ± 0.2) × 10⁸ L mol^-1 s^-1; with ^•O
