【Abstract】 In this work, the vibrational energy transfer of organic molecule CH2C12 was studied with laser induced fluorescence method for the first time. The activation and deactiva-tion rate constants of modes v_s and v₃/v₉ of pure CH₂C12, as well as the effect of rare gases on the deactivation processes for v₃/v₉, were obtained. The relative propablities of energy transfer from v₃/v₉ vibrational modes of CH2Cl₂ to translational degree of freedom were calculated by means of SSH theory for the collision relaxation processes of CH2Cl2-rare gas mixtures. A vibrational energy transfer channel in CH2C1₂ is also discussed.更多还原
