Linalool reacts rapidly in the gas phase in the troposphere with OH radicals, NO3 radicals, and O-3. With a calculated lifetime due to these reactions of similar to 1 h Or less. The products of these gas-phase reactions have been studied in similar to 6500-7900-L Teflon chambers using gas chromatography, in situ Fourier transform infrared absorption spectroscopy, and direct air sampling atmospheric pressure ionization tandem mass spectrometry. The products identified and their formation yields are as follows: from the OH radical reaction, acetone, 0.505 +/- 0.047; 6-methyl-5-hepten-2-one, 0.068 +/- 0.006; 4-hydroxy-4-methyl-5-hexen-1-al (or its cyclized isomer), 0.46 +/- 0.11; from the NO3 radical reaction, acetone, 0.225 +/- 0.052; 4-hydroxy-4-methyl-5-hexen-1-al (or its cyclized isomer), 0.191 +/- 0.051; and a non-quantified nitrooxycarbonyl; from the O-3 reaction, acetone, 0.211 +/- 0.024; 4-hydroxy-4-methyl-5-hexen-1-al (or its cyclized isomer), 0.85 +/- 0.14; 5-ethenyldihydro-5-methyl-2(3H)-furanone, 0.126 +/- 0.025; and HCHO, 0.36 +/- 0.06. The formation routes to these products and the reaction mechanisms are discussed. Despite the complexity of linalool, a C-10-hydroxydiene, the reaction products observed and quantified account for a significant fraction of the carbon reacted (especially for the OH radical and O-3 reactions), with the carbon balances being 53 +/- 8% for the OH radical reaction in the presence of NO, 20 +/- 4% (plus the non-quantified, but anticipated to be major, nitrooxycarbonyl) for the NO3 radical reaction, and 78 +/- 10% for the O-3 reaction.
