Ionization Potentials and Reactivity of Coinage Metal Clusters

Article abstract of DOI:10.1021/j100182a013

The ionization potentials of several homoatomic and heteroatomic coinage metal clusters have been determined utilizing charge-transfer bracketing and Fourier transform ion cyclotron resonance (FTICR) mass spectrometry.The clusters studied were Ag_n, Au_n, Cu_m, and Ag_kCu_l, where n = 2,3,5, m = 2,3, and k and l = 1,2.Atomic ionization potentials were also verified for each of the above metals as a test of the bracketing method.This work represents one of the first measurements of adiabatic ionization potentials for any of the above clusters.A number of additional reactions were observed between several of the charge-transfer agents and metal cluster ions, including some which resulted in metal-metal bond cleavage.
