Abstract
Tunable laser photodissociation spectroscopy and photofragment imaging experiments are employed to investigate the dissociation energies of the Fe⁺(acetylene), Fe⁺(benzene), and Fe⁺(benzene)₂ ion-molecule complexes. In the spectroscopy experiment, continuous dissociation is observed above a certain energy threshold throughout the visible wavelength region for all three complexes. Photofragment imaging of the Fe⁺ photoproduct in the cases of Fe⁺(acetylene) and Fe⁺(benzene), and imaging of the benzene⁺ charge transfer photoproduct of Fe⁺(benzene), provide upper limits on the dissociation energies of these two complexes. The dissociation energies measured from this two-pronged approach agree nicely with values determined previously by collision-induced dissociation. However, these values are inconsistent with those produced from computational chemistry at the DFT level, despite the implementation of functionals recommended for transition metal chemistry.
