“…From the seven exothermic product channels for CH + 0 2 listed in Table I the channel forming electronically exited OH ( A ' Z + ) could be verified as one major product path at room temperature by measurements of the OH chemiluminiscence [32,33] during the reaction P( 1 1). From LIF-measurements Lin (341 concluded some evidence for the formation of vibrationally exited CO and COz but the relative weights of the energetically possible product channels, see Table I, are still unknown.…”

The formation and consumption of CH radicals during shock‐induced pyrolysis of a few ppm ethane diluted in argon was measured by a ring‐dye laser spectrometer. Absorption‐over‐time profiles, measured at a resonance line in the Q‐branch of the A2Δ − X2Π band of CH at λ = 431.1311 nm, were recorded and transformed into CH concentrations by known absorption coefficients. By adding some hundred ppm of CO2 or O2 to the initial mixtures, the CH concentration profiles were significantly perturbed. Both the perturbed and unperturbed CH concentration profiles have been compared with calculations based on a reaction kinetic model. A sensitivity analysis revealed that the perturbation process was dominated by direct reactions of CH with the added molecules. By fitting calculated to observed CH profiles the following rate coefficients were obtained The experiments were performed in the temperature range between 2500 K and 3500 K. © 1996 John Wiley & Sons, Inc.

“…[5][6][7][8][9][10][11][12][13][14][15][16][17][18] No pressure dependence of the rate coefficient has been found in this range, and for (700 K < T > 300 K), the rate coefficient has a constant value, as it does in the 2200-3500 K range, though here it is a factor of 3-4 higherll-12 than the room temperature value. The room temperature value lies in the range (2.3-5.9) x 10-11 C m3 molec-1 s~l amid the various reported works, except that of Duncanson and Guillory9 who reported a much smaller value of 2.1 x 10-12 C m3 molec-1 s -l.…”

ABSTRACTProduction of CO vis-uv-chemiluminescence has been observed for the first time in the gas phase reaction of photolytic-methylidyne radicals with molecular oxygen. A trace amount of CHBr3 vapor was photo-decomposed in a pulsed-photolysis reactor using a 248-nm laser under multi-photon-dissociation conditions to produce the CH(X2n) radicals in an excess of O2 in diluent helium carrier gas at 2.0 torr and 298 K. The time resolved chemiluminescent traces due to characteristic CO(A-X), CO(a-X) and CO(d-a) vibronic emissions were recorded at several band positions. 147.8 nm was the shortest wavelength at which CO emission was recordable.The integrated intensities of the CO emissions showed a quadratic dependence on the photolysis fluence employed as did the OH(A-X) emission in the (1-0) band. The dependence of the OH and CO chemiluminescence on [O2] was studied to obtain the rate coefficient(s) for the Approved for Public Release, Distribution is Unlimited chemiluminescent reaction(s). The data is best interpreted by postulating that CH(v">0) reactions with 02 lead to the observed CO-emissions as well as the well-known OHchemiluminescence.
