The Study of V-E Energy Transfer in Ethylene and Na/K System

The kinetic study of the V-E energy transfer from the ethylene molecule to sodium and potassium atoms have been successfully carried out with a new approach. In this work we proposed an energy group model for description of the kinetic processes between ethylene and alkali atoms. Based on this model, the V-E energy transfer rate constants and their temperature dependence for all the systems were obtained. It is found that these rate constants are nearly as fast as the gas kinetic rate constants and the temperature dependence is rather weak. The experimental results show ’that the suggested kinetic energy group model is reasonable and the fate equations correctly described the collision processes. The harpooning mechanism may be used to interpret above V-E energy transfer processes.
