Abstract Sabinaketone is one major photooxidation product of sabinene, an important biogenic volatile organic compound. This article provides the first product study and the second rate constant determination of its reaction with OH radicals. Experiments were investigated under controlled conditions for pressure and temperature in the LISA indoor simulation chamber using FTIR spectrometry. Kinetic study was carried out at 295 ± 2 K and atmospheric pressure using the relative rate technique with isoprene as the reference compound. The rate constant was found to be k sabinaketone + OH = (7.1 ± 1.0) × 10 −12 molecule −1 cm 3 s −1 . Acetone and formaldehyde were detected as products of the reaction with the respective yields of R acetone = 0.9 ± 0.2 and R HCHO = 1.2 ± 0.3. © 2007 Wiley Periodicals, Inc.
