Abstract
We present a study of the photodissociation spectra of Sr+ solvated by the polar molecules H20 and NH3. Mass selection allows us to control the number of solvent molecules bound to the metal center. The electronic spectra are interpreted using ligand field and charge transfer concepts. For clusters with NH3 as the solvent, the spectra undergo large red shifts with increasing cluster size, with absorption maxima moving from 590 nm for n=1 to 1.4μ for n=6. Absolute cross section measurements show that <r2> for the valence electron increases by a factor of nearly 20 as n increases from 1 to 5. This increase is confirmed in molecular dynamics simulations by Martyna and Klein, suggesting that the initial stages of ionization and solvation involve Rydberg state formation.
