| description | Photodetachment spectroscopy of the FH2‾ and FD2‾ anions allows for the direct observation of reactive resonances of the benchmark reaction F + H2 →HF + H. Using cooled anion precursors and a high-resolution electron spectrometer, we observe several narrow peaks not seen in previous experiments. Theoretical calculations, based on a highly accurate F+H2 potential energy surface, convincingly assign these peaks to resonances associated with quasi-bound states in the HF+H and DF+D product arrangements, and with a quasi-bound state in the transition state region of the F+H2 reaction. The calculations also reveal quasi-bound states in the reactant arrangement, which have yet to be resolved experimentally. |
