We report a kinetic study of association reactions of nickel atoms with carbon monoxide, ethene, propene and 1-butene in carbon dioxide buffer gas in the pressure range 1–600 Torr at 296 K. RRKM theory is used together with results of previous ab initio electronic structure calculations to interpret association rate coefficients in terms of binding energies of 1:1 complexes. The binding energy of NiC2H4
我们报告了在296 K压力范围为1–600 Torr的二氧化碳缓冲气体中镍原子与一氧化碳,乙烯,丙烯和1-丁烯的缔合反应的动力学研究。RRKM理论与先前的从头算的结果一起使用电子结构计算,以1:1配合物的结合能来解释缔合速率系数。NiC 2 H 4在0 K的结合能估计为35.5±5 kcal mol -1。简要讨论了复合物的激发电子态在缔合反应中的作用。
