用时间分辨窝里叶红外发射谱研究了高振动激发态CO向C2H2的传能，得到了CO（v＝1－3）各振动态布展及其随时间的变化,利用微分法解出弛豫微分方程组，获得CO（v=1-3）向C2H2的传能速率常数分别为：2．0±0．1，6.0±0．2和9．1±0.8（10-13cm3·molecule-1·s-1）．传能速率随着振动量子数的增加而迅速增加．CO的振动能应向C2H2的对称伸缩模v2近共振V－V传递．传能过程中还可能形成二聚体络合物，加速了CO（v）向C2H2的传能．用abinitio方法确定了CO...C2H2两种可能的直线构型．
The time-dependent cellular fission infrared emission spectra were used to study the energy transfer from CO to C2H2. The CO (v = 1-3) vibrational state distribution and its variation with time were obtained. The differential method was used to solve the relaxation In the differential system, the constants of the energy transfer rates from CO (v = 1-3) to C2H2 are: 2.0 ± 0.1, 6.0 ± 0.2 and 9.1 ± 0.8 (10-13 cm3 · molecule-1 · S-1). The rate of energy transfer increases rapidly with the increase of the vibrational quantum number. The vibrational energy of CO should be transferred to the symmetrical stretching mode of C2H2 v2 near resonance V-V. It is also possible to form dimeric complexes during energy transfer, accelerating the transfer of CO (v) to C2H2. Two possible linear configurations of CO ... C2H2 were determined by the abinitio method.
