Abstract

Guided-ion beam mass spectrometry is used to study the ligand exchange andcollision induced dissociation reactions of Fe+(N-2) with Ar, Kr, Xe, CO2,and CD4 and Fe+(CO2) with Kr, Xe, and N-2 as a function of kinetic energy. Analysis of the energy dependent cross sections provides threshold energies for both types of reactions. These thresholds can be converted to the following 0 K bond dissociation energies: D-0(Fe+-Ar) = 0.11 +/- 0.08 eV, D-0(Fe+-Kr)= 0.31 +/- 0.07 eV, D-0(Fe+-Xe) = 0.44 +/- 0.06 eV, D-0(Fe+-N-2) = 0.55 +/- 0.04 eV, and D-0(Fe+-CO2) = 0.62 +/- 0.04 eV. Our results are compared with experimental and theoretical values found in the literature. Thesecomparisons suggest that Fe+(CO2) has a linear structure in agreement withtheoretical calculations.
