    Notes: Abstract The formation yields of nine carbonyl products are reported from the gas-phase OH radical-initiated reactions (in the presence of NO x ) and the O3 reactions with seven monoterpenes. The products were identified using GC/MS and GC-FTIR and quantified by GC-FID analyses of samples collected on Tenax solid adsorbent cartridges. The identities of products from camphene, limonene and β-pinene were confirmed by comparison with authentic standards. Sufficient quantities of products from the 3-carene, limonene, α-pinene, sabinene and terpinolene reactions were isolated to allow structural confirmation by proton NMR spectroscopy. The measured total carbonyl formation yields ranged from non-detectable for the OH radical reaction with camphene and the O3 reactions with 3-carene and limonene to ∼0.5 for the OH radical reaction with limonene and the O3 reaction with sabinene.

    Notes: Abstract Rate constants for the gas-phase reactions of OH radicals with nopinone (6,6-dimethylbicyclo[3.1.1]heptan-2-one) and camphenilone (3,3-dimethylbicyclo[2.2.1]heptan-2-one) and for the reactions of 4-acetyl-1-methylcyclohexene with OH and NO3 radicals and O3 have been measured at 296±2 K. The rate constants (cm3 molecule−1 s−1 units) obtained were, for reaction with the OH radical: nopinone, (1.43±0.37)×10−11; camphenilone, (5.15±1.44)×10−12; and 4-acetyl-1-methylcyclohexene, (1.29±0.33)×10−10; for reaction with the NO3 radical: 4-acetyl-1-methylcyclohexene, (1.05±0.38)×10−11; and for reaction with O3: 4-acetyl-1-methylcyclohexene, (1.50±0.53)×10−16. These data are used to calculate the tropospheric lifetimes of these monoterpene atmospheric reaction products.
