Rate Coefficients for the Reaction of C2H With O2 at 90 K and 120 K Using a Pulsed Laval Nozzle Apparatus
S Lee, S R. Leone
solute rate coefficients for the reaction of C2H with O2 are measured at 90K by using a pulsed Laval nozzle apparatus with laser ionization, time-of-flight mass spectrometry (TOF-MS). The C2H radicals are generated by laser photolysis of C2H2 at 193 nm, and the products of the reaction with O2 and C2H2, HCCO and C4 H 2, respectively, are directly detected by laser ionization at 118 nm. Rate coefficients of (9.0 2.0) x 10-11 and (5.0 1.5) x 10-11 cm3 molecule-1 s-1 are obtained at 90K and 120K for the C2H + O2 reaction, respectively, by detecting the rise of the product HCCO.
