dc.description.abstractWe report the measurement of the electron binding energies of size selected IBr$^-$(CO$_2$)$_n$, n$<$10 cluster anions. The data are interpreted using {\it ab initio} calculations and Franck-Condon simulations to assist in the assignment of the photoelectron spectra. The IBr(CO$_2$)$_n$ anion are formed by a 1 kV electron impact on dilute IBr and CO$_2$ in a pulsed supersonic expansion. Time-of-flight mass spectrometry allows a size-selected cluster anion to interact with a pulsed ultraviolet laser radiation tunable between 210 and 320 nm. The photodetached electrons are energy analyzed using a photoelectron imaging spectrometer operating in the velocity map imaging mode. The spectrometer determines electron kinetic energy, with an energy resolution of 2.5 percent. Trends in electron binding energy as a function of size will be discussed in regard to the trend that develops upon the addition of each cluster, and compared to previous photoelectron spectroscopy of I$_{2}^{\!\!\!-}$(CO$_2$)$_n$ clusters.
