Rate constants for the gas‐phase reactions of O( 3 P) atom with a series of monoterpenes have been determined at ambient temperature (ca. 302–309 K) and atmospheric pressure using a relative rate technique. Using the literature rate constants for O( 3 P) + isobutene, cis and trans ‐2‐butene, 3‐methyl‐1‐butene, 2‐methyl‐2‐butene, and 2,3‐dimethyl‐2‐butene as the standards, the O( 3 P) rate constants derived for the terpenes (in units of 10 −11 cm 3 molecule −1 s −1 ) are 2.8 ± 0.4 for α‐pinene, 2.8 ± 0.5 for β‐pinene, 3.1 ± 0.5 for Δ 3 ‐carene, 3.5 ± 0.5 for 2‐carene, 2.6 ± 0.5 for camphene, 7.6 ± 1.2 for d ‐limonene, 9.0 ± 1.6 for γ‐terpinene, and 10.7 ± 1.6 for terpinolene. The relative rate constants in this work agreed with literature values to within ± 10% for the standard alkenes, and to within ± ca. 35% for the terpenes. © 1996 John Wiley & Sons, Inc.
