We present the measurements of quenching rate constants of CH(A~2△) radical by O_2, cyclo-C_6H_(12) and CS_2 molecules. The time-resolved spectra of emission CH(A~2△-X~2Π) was monitored. The measured quenching rate constants are as follows.
k_q(O_2)=(2.8±0.5)×10~(-11) cm~3·molec~(-1)·s~(-1)
k_q(cyclo-C_6H_(12))=(2.7±0.4)×10~(-10) cm~3·molec~(-1)·s~(-1)
k_q(CS_2)=(4.0±0.6)×10~(-10) cm~3·molec~(-1)·s~(-1)
The value of k_q(O_2) is in od agreement with previous works. The rate constants for quenching by cyclo-C_6H_(12) and CS_2 are reported for the first time.
