摘要: Abstract Singlet methylene ( 1 CH 2 ) and the formyl radical (HCO) have been studied in a premixed flat flame of 4 air by cavity ring-down spectroscopy at atm. The absorption lines lie same spectral region for both species. radicals were probed via b B (0,13,0) ←a A (0,0,0) band 622 nm HCO A′ (0,9,0) ←X A″ 615 nm. Absolute concentrations obtained various heights above burner compared to numerical simulations using GRI-Mech 2.11 3.0 mechanisms, showing relatively good agreement.
