Abstract
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.
