Popis:	The dependence on rotational level excitation of the cross sections for removal of CH(A2Δ, v=0) (and the deuterated substitute CD) by CO is measured. Cross sections are found to decrease with increasing rotational level energy. The removal cross sections of the excited CH radical take values that decrease from 6.1 to 1.3 A2 for the rotational levels N=4 and 17, respectively. The quenching cross sections of CD(A2Δ, v=0) by CO have slightly smaller values. Quenching cross sections of CH(A2Δ, v=0) by H2 and Xe have similar dependencies on rotational energy than those observed for the deuterated radical. The rotationally averaged cross sections for CO are about twice larger than for Xe and nearly one order of magnitude larger than for H2.
