Study of the Interplay Among Non -Covalent Interactions in Structural Determination of Gas Phase Cluster Ions

The cesium and lithium ions were also investigated with benzene and water. Unimolecular dissociation rates were used to determine the most labile species and therefore a possible structural change. In the vibrational spectra of Li+(Benzene)n(Water)1--4 clusters, pi-H bonding bands dominated, while water-water hydrogen bonding features dominated the spectra of Cs+(Benzene)n(Water)1--4 clusters. The lithium ion retains a full solvent shell of four waters, while the cesium ion becomes partially dehydrated. This study exemplifies the utility of vibrational spectroscopy to characterize intermolecular interactions with different ions and solvents.
