Abstract

The kinetics and absolute rate constants of the gas-phase reaction of the hydroxymethyl radical (C[H.sub.2]OH) with molecular oxygen were studied using laser photolysis/near-IR absorption spectroscopy. The results showed slight negative temperature dependence in the measured temperature region.

Abstract

Cavity ring-down spectroscopy (CRDS) was applied in several fuel-rich, one-dimensional, premixed [C.sub.3][H.sub.6]/[O.sub.2]/Ar flames at 50 mbars (37.5 torr) to measure absolute OH, HCO, and [sup.1]C[H.sub.2] concentration as well as temperature as a function of stoichiometry. Although these flames near the sooting limit present a complex chemical environment, significant spectral interferences were found to be absent. Specific aspects of the CRDS technique for measurement of temperature and radical concentration profiles are discussed; and the results are analyzed in comparison with flame model simulations. OCIS codes: 120.1740, 300.1030, 120.6780.
