    Kinetics and mechanism of the reaction of CH3O with NO (1994)
    New York, NY : Wiley-Blackwell

    Notes: The kinetics of the reaction of CH3O with NO and the branching ratio for HCHO product formation, obtained as ΓHCHO = (Rate of HCHO formation) / (Rate of CH3O decay), have been studied using a discharge flow reactor. Laser induced fluorescence has been used to monitor the decay of the CH3O radical and the build-up of the HCHO product. Overall rate constants and product branching ratios were measured at room temperature over the pressure range of 0.72-8.5 torr He. Three reaction mechanisms were considered which differed in the routes of HCHO formation: (i) direct disproportionation; (ii) via an energized collision complex; or (iii) both reaction routes. It has been shown that data on the pressure dependence of the overall rate constant are not sufficient to distinguish between these mechanisms. In addition, an accurate value of ΓHCHO∞ is required. Analysis of the available experimental data provided 0.0 and about 0.1 as the lower and upper limit for ΓHCHO∞, respectively. Since the rate constants derived for CH3ONO formation were not sensitive to the value assumed for ΓHCHO∞, kCH3ONO° = (1.69 ± 0.69) × 10-29 cm6 molecule-2 s-1 and kCH3ONO∞ = (2.45 ± 0.31) × 10-11 cm3 molecule-1 s-1 could be derived. The rate constant obtained for formaldehyde formation when extrapolated to zero pressure is kHCHO0 = (3.15 ± 0.92) × 10-12 cm3 molecule-1 s-1. © 1994 John Wiley & Sons, Inc.

    Notes: The photolysis was investigated at 313 nm wavelength, 253-529 K temperatures, and 4 × 10-11-2 × 10-9 mol·photon/cm2·sec light intensities by determining the quantum yields of 20 reaction products. Primary quantum yields for the seven primary processes and rate constant ratios, rate constants, and Arrhenius parameters for secondary processes were derived on the basis of the suggested reaction scheme. The dependence of the quantum yields of the four major primary processes on experimental conditions was established.

    Gas phase decomposition and isomerization reactions of 2-pentoxy radicals (1986)

    Notes: The rate of decomposition of 2-pentoxy radical to acetaldehyde and n-propyl radical has been studied in the presence of NO in competition with nitrite formation at and above 200 kPa pressure over the temperature range of 363-413 K. The rate coefficient for the decomposition is given as log(kla/s-1) = (14.2 ± 0.4) - (13.8 ± 0.8) kcal mol-1/RT ln 10. Isomerization of 2-pentoxy radical by 1,5-hydrogen shift has been investigated in the range 279-385 K in competition with the decomposition in a static system, with methyl radicals present in high concentration to ensure trapping of the isomerized free radicals. The rate coefficient for isomerization is given as log(k3/s-1) = (11.1 ± 0.7) - (9.5 ± 1.1) kcal mol-1/RT ln 10. The implications of the results for atmospheric chemistry are discussed.

    Isomerization of n-hexyl and s-octyl radicals by 1,5 and 1,4 intramolecular hydrogen atom transfer reactions (1987)

    Notes: n-Hexyl and s-octyl radical isomerizations by intramolecular hydrogen atom shift have been studied in the presence of high methyl radical concentration where isomerized alkyl radicals reacted predominantly by combination and disproportionation reactions with methyl radicals.By assuming the rate coefficient of 1-hexyl radical recombination to be equal to that of ethyl self-combination, the rate coefficient of log(k1/s-1) = (9.5 ± 0.3) - (11.6 ± 0.3) kcal mol-1/RT ln 10 has been derived for the 6sp isomerization of n-hexyl radicals, 1-hexyl → 2-hexyl (1).Investigation of s-octyl radical isomerization was complicated by fast interconversion between 3-octyl, 2-octyl, and 4-octyl radicals. Use of the methyl trapping technique and systematic variation of methyl radical concentration made possible the determination of log(k2/s-1) = (9.4 ± 0.7) - (11.2 ± 1.0) kcal mol-1/RT ln 10 for the 6ss isomerization of 3-octyl and the estimation of log(k3/s-1) = 10.5-17 kcal mol-1/RT ln 10 for the 5ss isomerization of 2-octyl radicals, where 3-octyl → 2-octyl (2), and 2-octyl → 4-octyl (3).

    Notes: The kinetics of the reactions of hydroxy radicals with cyclopropane and cyclobutane has been investigated in the temperature range of 298-492 K with laser flash photolysis/resonance fluorescence technique. The temperature dependence of the rate constants is given by k1 = (1.17 ± 0.15) × 10-16 T3/2 exp[-(1037 ± 87) kcal mol-1/RT] cm3 molecule-1 s1 and k2 = (5.06 ± 0.57) × 10-16 T3/2 exp[-(228 ± 78) kcal mol-1/RT] cm3 molecule-1 s-1 for the reactions OH + cyclopropane → products (1) and OH + cyclobutane → products (2), respectively. Kinetic data available for OH + cycloalkane reactions were analyzed in terms of structure-reactivity correlations involving kinetic and energetic parameters.
