摘要：

The chemistry of methyl iodide on Ni(100) surfaces has been studied by using x-ray photoelectron spectroscopy (XPS). Methyl iodide adsorption is molecular below 100 K, but the C-I bond begins to cleave around 120 K and is completely broken by 160 K. The activation energy for the C-I bond scission was estimated to be about 3.5 kcal/mol based on results from isothermal XPS experiments.
