From: The effect of oxygen concentration on the speciation of laser ablated uranium
In-situ FTIR spectra of collected particulates after ablation of uranium in 100% O2 (black) and 18O2 (red). The three am-UOx (3 ≤ x ≤ 4) features, indicated with dashed lines, shift to lower frequencies upon 18O-substitution, as expected with oxygen-containing molecules. Furthermore, spectral features of ozone and carbon dioxide also shift confirming their formation during ablation. Spectra are offset for clarity.
