Rate constants for the quenching of CH(A 'A, v'=O) by OS, cyclc~-C~H,~, n-CSH,2, n-&Hid, n-C7H,6, CH&, CHClp, CC& and CS2 molecules were measured by using the direct time-resolved technique. CH(A 'A) was produced by 266 nm ultraviolet laser photolysis and the time-resolved emission of CH(A 'A-\*X 'I

✦ Synopsis
Cross sections for collisional quenching of CH A 2A, u' =O were measured at 1300 K for a variety of collision partners. A laser pyrolysis/laser fluorescence technique was used, involving rapid heating by a pulsed CO2 laser and direct time decay of fluorescence excited by a pulsed dye laser. Where comparisons can be made, the cross sections are higher than those measured previously at room temperature.
