Abstract:
Femtosecond negative-ion photoelectron imaging spectroscopy allows the probing of dynamics resulting from solvation and photodissociation in both the time-resolved and solvent domains. First, the basic premise of photoelectron imaging shall be presented, followed by a discussion of qualitative approaches for interpreting photoelectron angular distributions as illustrated by application to the photoelectron images of S₂⁻ and CS₂⁻. The photoelectron images of CS₂⁻ serve as a reference for interpreting the results for homogeneous and heterogeneous solvation in CO₂ and OCS cluster anions. The effects of solvation upon the photoelectron angular distribution and the photoelectron energy spectrum are discussed in relation to (OCS)n⁻, OCS⁻·H₂O, (CO2)n⁻, and (CO₂)n(H₂O)m⁻. The (OCS)₂⁻ cluster anion images show evidence of competition of excited state decay pathways and coexistence of isomers. The evolution of photoelectron images, resulting from I₂Br⁻ dissociation shows the evolving electronic structure of the I⁻ channel as the anion dissociates.
