Laser induced fluorescence (LIF) was used to monitor OH in the presence of pinonaldehyde following its production by 248 nm pulsed laser photolysis of H2O2. The reaction exhibits a negative temperature dependence with an Arrhenius expression of k(1)(T) = (4.5 +/- 1.3) x 10(-12) exp((600 +/- 100)/T) cm(3) molecule(-1) s(-1); k(1)(297 K) = (3.46 +/- 0.4) x 10(-11) cm(3) molecule(-1) s(-1). There was no observed dependence of the rate coefficient on pressure. Our results are compared with previous relative rate determinations of k(1) near 297 K and the discrepancies are discussed. The state of knowledge for the atmospheric processing of pinonaldehyde is reviewed, and its role as a marker for alpha-pinene (monoterpene) chemistry in the atmosphere is discussed.
