On the absorption spectrum and stability of Ag32+ in aqueous solution

Pulse radiolysis results suggest that the very first steps of silver aggregation in water involve the formation of Ag32+. The authors present a mixed classical quantum simulation of the absorption spectrum of this aggregate which is in agreement with the exptl. spectrum. The formation and structure of this aggregate are discussed with the help of addnl. Monte Carlo and ab initio calcns. The results tend to confirm the formation of Ag32+
