The quenching rate constants of CH(A^2Δ) radical by alcohol molecules, such as C2H5OH, n-C3H7OH and n-C4H9OH, between 290K and 653K have been measured using laser photolysis of CHBr3 at 266nm to produce CH(A) radical and time-resolved fluorescence measurements. Under the simultaneous effects of multipole attractive potential and repulsive barrier, the temperature dependence is analyzed qualitatively based on a modified collision complex model.
