Rate constants for the gas-phase reactions of O(3P) 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(3P) + 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(3P) rate constants derived for the terpenes (in units of 10-11 cm3 molecule-1s -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.
