The infrared absorption spectra of uranyl oxalate and acetate in KBr matrices in the 4000-250 cm(-1) range have been examined. Special attention was devoted to the dependence of the IR spetra on the sample treatment temperature and to the shape of the v(3) bands appearing in the range of carbon dioxide laser radiation. Heat treatment up to some 270 degrees C leads to a narrowing of the band. Higher temperatures decompose the anions to carbon dioxide, while the uranyl ions are converted either to UO2 or potassium diuranate.
