The energy transfer process of highly vibrational states of CO with C2H2 has been studied by the Time -resolved Fourier Transform Infrared Emission Spectroscopy. The vibrational population of CO(v=1-3)were obtained by the simulations of the IR emission spectra. Differentiation method was used to calculate the quenching rate constants of CO(v=1-3)which are:2.0±0.1，6.0±0.2and 9.4±0.8(10-13cm3.molecule-1.s-1), respectively. The most possible energy transfer channel is the transfer of CO(v)to C2H2(v2). Dimer complexes may be formed in the collisional process. The equilibrium structures and lifetime of the complexes were estimated by ab initio computation and V-V/R theory.
