Less than ten years ago, the gas phase spectroscopy of organometallic radicals was, except for diatomics and other closely related species, essentially non-existant. The situation changed dramatically with the reports of laser induced fluorescence (LIF) spectra of organometallic radicals by Bemath and co-workers. They prepared a number of species in a Brodia oven reactor wherein a metal vapor, produced from equillibrium heating of a metallic solid, is reacted with a suitable reagent to form an organometallic radical. The species produced were at ambient temperature or above and oftentimes their LIF spectra were quite congested; however, a number of very interesting observations were made concerning their electronic spectra and structure, and the foundation for future experiments was firmly laid. Somewhat after the promising experiments of Bernath and co-workers, our laboratory pioneered the production of similar organometallic radicals in a supersonic free jet expansion. The cooling of the organometallic radicals by the jet to a few degrees Kelvin greatly simplified many of their LIF spectra and allowed for detailed analysis.
