Abstract
AbstractThe reaction: was investigated in a quasistatic flash photolysis system at room temperature in the pressure range 0.5 ≦ p/mbar < 1.5 with He as the main carrier gas. The concentrations of CH2(ã1A1) produced in laser photolysis of CH2CO at λL = 308 nm, and the absolute concentration of the reaction product OH were monitored by laser induced fluorescence. In addition the population of the rotational states of the initial product OH (X, n̈ = 0, K) was measured. The time delay between photolysis and probe pulse delivered the time resolution. — The overall 1CH2 depletion rate determined from Stern‐Volmer plots is k1 (298 K) = (1.3 ± 0.2) · 1014 cm3/mol s. The channel: is determined to be the dominant reaction path in the range 0.5 ≦ k1a/k1 ≦ 1.0. The physical deactivation is found to be less than 50% of k1, in agreement with previous measurements. The bearing of these results on the reaction CH3 + OH and on the thermal CH3OH dissociation is briefly discussed.
