Reactions of Laser-Ablated Molybdenum and Tungsten Atoms with Dioxygen. Resolved Infrared Spectra of Natural Molybdenum and Tungsten Isotopic Oxides in Argon Matrices

Laser-ablated molybdenum and tungsten atoms were reacted with dioxygen and 18O-substituted dioxygen. The products of these reactions were isolated in solid argon matrices at 10 K and studied by matrix infrared spectroscopy. Analysis of spectra enabled identification of reaction products, which inclu...

Zusammenfassung:Laser-ablated molybdenum and tungsten atoms were reacted with dioxygen and 18O-substituted dioxygen. The products of these reactions were isolated in solid argon matrices at 10 K and studied by matrix infrared spectroscopy. Analysis of spectra enabled identification of reaction products, which included MoO2, (O2)MoO2, MoO3, WO, WO2, (O2)WO2, and WO3. Resolution of isotopic splitting due to natural isotopic abundance of the metal verified the presence of a single metal atom in these molecules and allowed for calculation of bond angles for the molybdenum and tungsten dioxide molecules and their dioxygen complexes.
