Photodissociation And Spectroscopy Of Gas Phase Bimetallic Clusters PDF Download

The general goals of this research project are (1) to synthesize novel bimetallic clusters in the gas phase; (2) to characterize their geometry, electronic structure, and chemical bonding; and (3) to compare these heterogeneous systems to corresponding pure component clusters. Clusters are synthesized by pulsed laser vaporization of solid metal rods coincident with laser photolysis of volatile metal complexes (e.g., metal carbonyls). Two techniques are used to characterize cluster properties: resonant two-photon ionization spectroscopy (R2PI) of neutral clusters and laser photodissociation spectroscopy of cluster ions. The project focuses on the selected mixtures of iron, chromium, and molybdenum with bismuth, aluminum and silver to probe a variety of heterogeneous effects in transition metal-main group metal mixtures.
