Infrared, Raman, and visible spectroscopic studies of Zn and Cd matrix reactions with ozone. Spectra of metal ozonides and oxides in solid argon and nitrogen

Abstract

Reactions of zinc and cadmium atoms with ozone during condensation with excess nitrogen or argon produced B+O3− ion-pairs having infrared, Raman, and optical spectra similar to the analogous alkali and alkaline earth metal species. Additional infrared and Raman evidence was found for a different B+O3− ion-pair geometry. Mercury arc photolysis reduced ozonide absorptions and produced new 810 cm−1 zinc isotopic triplets which showed the appropriate 18O shifts for ZnO, and a new 719 cm−1 band which showed the proper 18O displacement for CdO. This nitrogen matrix work provides good measures of the yet-to-be-observed gas-phase fundamentals of these high temperature oxides.
