The rate coefficients for the reactions of ozone with 2-carene and 3-carene have been measured at 760 Torr of air and 299 +/- 6K using both absolute and relative methods. The data obtained are (in units of x 10(-17) cm(3) molecule(-1) s(-1)): k(2-carene) = 23.8 +/- 1.0, k(3-carene) = 3.7 +/- 0.2. The present work supplements the kinetic database of 2-carene and 3-carene using varied conventional experimental methods. The results are compared with the literature data and discussed with respect to atmospheric chemistry. (C) 2015 Elsevier B.V. All rights reserved.
