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.

The magnesium–ozone reaction has been studied by condensing the reagents with nitrogen at 14 K. Isotopic substitution with 26Mg, 16,18O3, and 18O3 has identified infrared absorptions due to two different Mg+O−3 species, MgO2 and MgO. Six isotopic MgO molecules support this infrared detection of MgO which shows a blue matrix shift. Analogous argon matrix reactions produced only Mg+O−3 and two isomeric MgO3 species.
