Influence of cluster size and ion activation method on the dissociation of cesium iodide clusters

The gas-phase dissociation of cesium iodide clusters was studied by collision-induced dissociation (CID) and surface-induced dissociation (SID) in a quadrupole time-of-flight mass spectrometer. SID was found to deposit more internal energy into these clusters, providing access to alternative, high energy dissociation pathways.
