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 1% O2 (blue). Formation of am-UOx (3 ≤ x ≤ 4), indicated by the two uranyl stretching modes (790 and 910 cm−1), is observed in both high and low oxygen environments. Additional spectral intensity below 550 cm−1 suggests a different uranium oxide, assigned to UO2, is also formed in 1% O2 atmospheres. Spectra are offset for clarity.
