    Atmospheric chemistry of the monoterpene reaction products nopinone, camphenilone, and 4-acetyl-1-methylcyclohexene (1993)

    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.

    Alkyl nitrate formation from the reaction of a series of branched RO2 radicals with NO as a function of temperature and pressure (1987)
    Springer
    Journal of atmospheric chemistry 5 (1987), S. 91-102

    ISSN: 1573-0662

    Notes: Abstract Alkyl nitrate yields from the NO x photooxidations of neopentane, 2-methylbutane and 3-methylpentane have been determined over the temperature and pressure ranges 281–323 K and 54–740 torr, respectively. The formation of the alkyl nitrates is attributed to the reaction pathway (1b) $${\text{RO}}_{\text{2}} + {\text{NO}}^{{\text{ }}\underrightarrow {\text{M}}} {\text{ RONO}}_{\text{2}}$$ and rate constant ratios k 1b/(k 1a+k 1b) are estimated, where (1a) is the reaction pathway (1a) $${\text{RO}}_{\text{2}} + {\text{NO}} \to {\text{RONO}}_{\text{2}} .$$ A method for estimating this rate constant ratio for primary, secondary and tertiary alkyl peroxy radicals is presented.
