Absorption Spectra of Molybdenum Oxide Molecules and Molybdenum Atoms in Neon and Argon Matrices at Four Degrees K.

摘要

MoO2, MoO3, and (MoO3)(2-5) have been trapped in neon and argon matrices and studied spectroscopically in the infrared, visible, and ultraviolet regions. No evidence for a MoO molecule was found and no definite electronic spectra were observed for any of these molecules, in sharp contrast to the spectra of WO and WO2 produced and isolated in the same way. The molybdenum oxide molecules were prepared by vaporization of the solid oxides or by passing 16O2 and 18O2 over molybdenum metal at 2000 to 2600 K.
