Time-resolved electron detachment imaging of the I^- channel in I₂Br photodissociation

The use of time-resolved negative-ion photoelectron imaging spectroscopy for the evolution of the I^- channel of I₂Br^- photodissociation was analyzed. The 388 nm pump-388 nm probe photoelectron images showed details of the electronic structure transformation from the excited molecular anion to the atomic-anion fragment. It was stated that the dynamics of the photodissociation can be divided into two stages. In the first stage, the excess-electron wave function transforms from a molecular orbital to a localized atomic orbital. The second stage involves exit-channel dynamics where fragment interactions persists.
