Abstract
The ability of iron ions to activate methane is studied in detail by using a guided ion beam tandem mass spectrometer. State-specific results for ground state Fe+(6D) and first excited state Fe+(4F) with methane are determined by varying the source conditions for Fe+. A more complete picture of the potential energy surface for this reaction is obtained by examining one of the reverse processes, FeCH2+ plus H2. The influence of ligands on the metal reactivity is also investigated for this reaction system. The reactions of methane with both FeCO+ and Fe(H2O)+ are examined with the latter exhibiting much greater reactivity. This result is attributed to the more favorable thermodynamics associated with the electronic configuration on Fe+ as induced by the H2O ligand.
