The absorption spectra of three different uranyl fluorides and uranyl chloride were investigated in powder form at liquid air temperature. For anhydrous fluoride and uranyl fluoride I, the data of bands are reported for the first time; for uranyl fluoride II, 32 additional bands were obtained. The absorption spectra of the anhydrous fluoride and fluoride I were found to consist of four and three systems, respectively. New analyses of bands are proposed for uranyl fluoride II and uranyl chloride on the basis of five and six systems, respectively. The wave-numbers of the 0,0 bands of the various systems obtained for the four compounds are as follows: anhydrous uranyl fluoride, 20,236, 20,386, 21,183, and 21,277 cm-1; uranyl fluoride I, 20,014, 23,160, and 23,429 cm-1; uranyl fluoride II, 20,080, 20,753, 21,217, 22,723, and 23,083 cm-1; uranyl chloride, 20,530, 21,107, 21,162, 21,234, 22,346, and 22,501 cm-1. For uranyl fluoride I and uranyl chloride, the wave-numbers of the fundamentals obtained from the analyses of the absorption spectra were correlated with those obtained in fluorescence, Raman, and infrared spectra by different workers.
