Transition metal cation-molecular complexes are produced in the gas phase environment of a molecular beam using laser ablation in a supersonic expansion. Complexes with carbon monoxide, carbon dioxide, water, acetylene, or benzene are produced by entraining small partial pressures of these molecules into an expansion of either argon or helium. A specially designed time-of-flight mass spectrometer is employed to analyze the ions produced and to mass select them for spectroscopy. Mass-selected ions are excited in the infrared region of the spectrum with a tunable IR optical parametric oscillator laser system to measure photodissociation spectroscopy in the 2000-4500 cm-1 region. Finally, infrared band patterns, combined with structures and spectra predicted by density functional theory, reveal the coordination and solvation interactions in these systems, and how binding to metal distorts the structures of small molecules.
