Abstract

Ab initio calculations are used to develop a potential energy surface for the IHI- molecule. Wavefunctions for some of the lowest vibrational states associated with this surface are then used to calculate transition state photodetachment spectra. The resulting spectra show small but important changes relative to those obtained previously with a harmonic force field. The spectra associated with IHI- vibrationally excited states are significantly different from the ground state, revealing more details of the IHI transition state structure.
