用TEACO2激光将C2H4分子激发到高振动激发态，高振动激发态的C2H4分子与基态的K原子碰撞发生振动态→电子态（V→E）传能过程，根据提出的能级组模型，对测得的时间分辨原子荧光信号进行处理，获得温度在453－663K范围内，C2H4－K体系中V→E传能速率的数量级为10－10／cm3·molecule－1·s－1，对应的碰撞传能截面约为30～80A2．随着反应温度升高，V→E传能截面减小．上述实验结果表明碰撞体间吸引相互作用在这种非共振的V→E传能过程中起主要作用．利用多极相互作用势下的碰撞络合物模型对实验结果进行了讨论．
Using TEACO2 laser to excite C2H4 molecule to a high vibrational excited state, the vibrational → electronic state (V → E) energy transfer occurs between the C2H4 molecule in the high vibrational excited state and the K atom in the ground state. According to the proposed energy level group model, The measured time-resolved atomic fluorescence signal was processed to obtain the temperature range of 453-663K, the C2H4-K system V → E energy rate of order of 10-10 / cm3 · molecule-1 · s-1, the corresponding Collision energy transfer cross-section is about 30 ~ 80A2. As the reaction temperature increases, V → E energy transfer cross section decreases. The above experimental results show that the inter-collision body attractive interaction plays a major role in this non-resonant V → E transfer. The experimental results are discussed using the collision complex model under the multi-polar interaction potential.
