| Chemical phenomena such as dissociative charge transfer have made generation of gas-phase solvated multiply charged metal ions challenging and, as a result, only a few spectroscopic studies have been reported. One method that has been successful in generating multiply charged species is Electrospray Ionization (ESI). We have adapted an ESI source in our laboratory to investigate the various non-covalent interactions in solvated multiply charged metal ion—ionophore systems, where the ionophore is a crown ether. We have performed infrared predissociaton spectroscopy on the Mn2+(18-crown-6)(CH3OH)n system where n=1-3 in the C—H and O—H stretching regions. In our infrared spectra, the onset of hydrogen-bonding is observed at n=2 and we have used ab initio calculations to show that hydrogen bonding, due to both methanol—crown ether and methanol—methanol interactions, plays an important role even when only a few solvent molecules are present in these complexes. |
