Laser ablated Zn and Cd atoms contain sufficient excess energy to react directly with O-2 to produce the subject molecules. A zinc isotopic triplet at 769.2, 766.8, 764.5 cm(-1) gave a doublet with statistical isotopic oxygen confirming the identification of ZnO. A previous resonance Raman fundamental at 769 cm(-1) is reassigned to ZnO, which suggests a green visible absorption for the zinc oxide molecule. A zinc isotopic triplet at 748.2, 744.4, 740.9 cm(-1) produced a triplet with statistical isotopic oxygen and isotopic shifts appropriate for the linear OZnO dioxide molecule. Cadmium is less reactive than zinc; infrared absorptions at 645.1 and 626.6, 625.4 cm(-1) exhibit proper oxygen isotopic behavior for assignment to CdO and OCdO and the latter showed partially resolved cadmium isotopic splittings.
