My education and research experience

Teaching Areas:

Physical, introductory, and environmental chemistry

Research Area:

My interests lie in the study of the gas-phase photochemistry of organometallic compounds highlighting direct metal-metal bonds. A focused NdYAG-pumped dye laser is directed into the vacuum chamber containing the metal vapor leads to create a multiphoton dissociation and ionization (MPD/MPI) process. The ionic products are detected by a time-of-flight (TOF) mass spectrometer. Specific spectroscopic and mechanistic information is obtained both from the analysis of the wavelength dependence of the metal-containing fragments created as well as in REMPI (resonance enhanced MPI) experiments in which the intensity of mass signals are recorded as the dye laser wavelength is scanned. Specific attention has been placed on Mn₂(CO)₁₀ and Co₃(CO)₉CCH₃. Extra information and background can be obtained by referring to the articles highlighted below.
