Due to the competition between intermolecular interactions (ion-molecule, molecule-molecule) in cluster ions, experimental and computational structural determinations can be quite challenging. Multiple minima on the potential energy surface, internal energy (effective temperature) effects and the dynamics of formation/stabilization add to the complexity of these systems. We will present recent results that demonstrate the synergistic interplay between infrared photodissociation spectroscopy and computational studies on a variety of cluster ion systems, including hydrated alkali metal ions, hydrated alkali ion-biomolecule complexes, and solvated divalent transition metal-crown ether complexes.
