✦ Synopsis

We report a kinetic study of association reactions of nickel atoms with carbon monoxide, ethene, propene and I-butene in carbon dioxide buffer gas in the pressure range l-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 NiC*H, at 0 K is estimated as 35.5 f 5 kcal mol-'. The role of excited electronic states of the complexes in the association reactions is briefly discussed.
