Abstract:

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 Agn, Aun, Cum, and AgkCu1, where n2, 3, and 5, m 2 or 3, and k and l 1 or 2. Atomic ionization potentials were also verified for each of the above metals as a test of the overall 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.
