Rate constants for the gas‐phase reactions of the four oxygenated biogenic organic compounds cis ‐3‐hexen‐1‐ol, cis ‐3‐hexenylacetate, trans ‐2‐hexenal, and linalool with OH radicals, NO 3 radicals, and O 3 have been determined at 296 ± 2 K and atmospheric pressure of air using relative rate methods. The rate constants obtained were (in cm 3 molecule −1 s −1 units): cis ‐3‐hexen‐1‐ol: (1.08 ± 0.22) × 10 −10 for reaction with the OH radical; (2.72 ± 0.83) × 10 −13 for reaction with the NO 3 radical; and (6.4 ± 1.7) × 10 −17 for reaction with O 3 ; cis ‐3‐hexenylacetate: (7.84 ± 1.64) × 10 −11 for reaction with the OH radical; (2.46 ± 0.75) × 10 −13 for reaction with the NO 3 radical; and (5.4 ± 1.4) × 10 −17 for reaction with O 3 ; trans ‐2‐hexenal: (4.41 ± 0.94) × 10 −11 for reaction with the OH radical; (1.21 ± 0.44) × 10 −14 for reaction with the NO 3 radical; and (2.0 ± 1.0) × 10 −18 for reaction with O 3 ; and linalool: (1.59 ± 0.40) × 10 −10 for reaction with the OH radical; (1.12 ± 0.40) × 10 −11 for reaction with the NO 3 radical; and (4.3 ± 1.6) × 10 −16 for reaction with O 3 . Combining these rate constants with estimated ambient tropospheric concentrations of OH radicals, NO 3 radicals, and O 3 results in calculated tropospheric lifetimes of these oxygenated organic compounds of a few hours. © 1995 John Wiley & Sons, Inc.
