The state-selective reactions of vibrationally excited CH ( X  2Π) with oxygen and nitrogen

The reaction rate constants for the reaction of CH (X 2Π, v″=0,1) with O2 and N2 have been measured. CH was produced by IR multiple photon dissociation of methanol and probed by laser induced fluorescence of the A(0,0) (431 nm) and A(0,1) (488 nm) transitions. The second order rate constants are k02...

description The reaction rate constants for the reaction of CH (X 2Π, v″=0,1) with O2 and N2 have been measured. CH was produced by IR multiple photon dissociation of methanol and probed by laser induced fluorescence of the A(0,0) (431 nm) and A(0,1) (488 nm) transitions. The second order rate constants are k02 (v″=0)=2.1×10−12 cm3 molecule−1 s−1, k02 (v″=1)=4.3×10−12 cm3 molecule−1 s−1, kN2 (v″=0)=7.1×10−14 cm−3 molecule−1 s−1, and kN2 (v″=1)=3.0×10−12 cm3 molecule−1 s−1. The rate constants for CH (v″=1) are the observed combined rate constants for reaction and vibrational relaxation.
