Time-resolved infrared emission spectra have been measured in the infrared multiple-photon decomposition of CClF₂CH₂Cl. The spectra were composed of emissions attributable to vibrationally excited HF^* and HCl^*. The emission yield of HF^* increased rapidly with an increase in the fluence, while the yield of HCl^* showed a maximum at 20 J cm⁻². These results suggest that the HF and HCl molecular elimination channels compete with each other in the unimolecular decomposition of highly vibrationally excited parent molecules. The stochastic trajectory calculations provided a satisfactory description of the fluence dependences of the HF and HCl yields observed here for CClF₂CH₂Cl and previously for CHClFCHClF.
