Abstract

Vibrational spectra of metal ion-solvent clusters have been obtained size-selectively, using mass spectrometric techniques. Metal ions (Cs⁺ and Na⁺) have been solvated by as many as 25molecules with solvents such as methanol and ammonia. Structural information such as solvenx shell sizes and solvent orientation have been inferred from the variation in solvent vibrational frequencies as a function of cluster size. Independent Monte Carlo simulations of the solvated ions, based on established ion-solvent, and solvent-solvent interaction potentials, are in good agreement with the experimental observations. The simulations in turn have indicated that hydrogen bonding may play a significant role in determining the solvent shell size for large ions. An informative picture of icroscopic ion solvation is the result of the interplay between experiment and simulation.
