The rotationally resolved electronic spectra of several conformers of 1-hexoxy and 1-heptoxy

Laser-induced fluorescence excitation spectra of five vibronic bands of 1-hexoxy and three bands of 1-heptoxy have been recorded in a jet-cooled environment. Experimental values of rotational constants for both the X and B states and components of the spin-rotational tensor for the X state were obtained by an analysis of the partially resolved rotational structure of the vibronic bands. Comparing these experimental results with quantum chemistry calculations, and using corresponding assignments of smaller alkoxy radicals as a guide, permitted unambiguous conformational assignments for the bands. The extension of similar assignments to larger alkoxy radicals is also discussed.

Direct investigations of reactions of 1-butoxy and 1-pentoxy radicals using laser pulse initiated oxidation: Reaction with O2 and isomerisation at 293 K and 50 mbar

The reactions of 1-butoxy and 1-pentoxy radicals were studied using time-resolved and simultaneous measurement of NO2 and OH concentrations in laser pulse initiated oxidation studies followed by numerical simulations of the concentration profiles. The alkoxy radicals were produced selectively by the excimer-laser photolysis of 1-butyl bromide and 1-pentyl bromide at 248 nm and subsequent reaction of the 1-alkyl radicals with O2 and NO. Whereas NO2 was detected by cw-LIF, OH was monitored by laser long-path absorption at 308 nm. All experiments were performed at 293 ± 3 K and a total pressure of 50 mbar. The reactions with O2 and the isomerisations via a 1,5-H-shift, viz., CH3CH2CH2CH2O + O2 → CH3CH2CH2CHO + HO2 (5) CH3CH2CH2CH2O → CH2CH2CH2CH2OH (6) CH3CH2CH2CH2CH2O + O2 → CH3CH2CH2CH2CHO + HO2 (25) CH3CH2CH2CH2CH2O → CH3CHCH2CH2CHOH (26) were investigated. Their rate coefficients were varied, utilizing the FACSIMILE integrator, until the best fits were obtained. Whereas in the case of 1- butoxy radicals absolute rate coefficients k(5) = (1.4 + 0.7) x 10-14 cm3 molecule-1 s-1 and k6 = (3.5 ± 2) x 104 S-1 could be derived, only limiting values for the 1-pentoxy radical reactions k25 ≤ 1 X 10- 13 cm3 molecule-1 s-1 and k26 ≥ 1.0 X 105 S-1 were obtained.
