| Abstract: | The collisional quenching rate constants of CH(A, V'=0) by Ar and CHBr_3 and CH(A, B, V'=0) by NO molecule were measured by means of laser photolysis of CHBr_3 molecule at 266 nm generating CH(A, B) radicals and monitoring the time-resolved signal of ethession CH(A, B→X). The dependence of quenching rate constant of CH(A, V'=0) by CHBr_3 on rotational state of CH(A) is presented. It is found that the quenching rate decreases with increasing rotational quantum number of CH(A). |
