“…Location of these bands (~540 and 470 cm −1 -Figs. 1 and 2) is close to those in IR spectra of α-U 3 O 8 and α-UO 3 [34,35] whose strictures are closely related [36].…”

“…Thus, the band with a maximum at~817-818 cm − 1 is due probably to ν 3 stretching modes of O_U V \ \O bonds whereas the band at 220-230 cm − 1 is responsible for ν 2 U\ \O stretching modes [26,34,35]. Results of deconvolution (Fig.…”

“…9) The strong band at about 745 cm À1 was assigned to the U-O stretching vibration of a continuous -O-U-O-Uchain. 13) The peaks at 519 and 470 cm À1 in the region 200-600 cm À1 were assigned to the E u band for the U-O stretch of U 3 O 8 , where E u indicates the double degeneracy representation of the space group C2mm, and these two peaks are shown clearly in Fig. 4.…”

The infrared spectra of uranium oxides (UO x) of various O/U ratios (x ¼ 2{2:667 in UO x) were measured by using ATR-FTIR in order to investigate the applicability of ATR technology to the characterization of uranium oxides or nuclear fuel. The samples of uranium oxides (UO x) were prepared by heating UO 2 powder in air atmosphere followed by weighing to determine the gains by oxygen. X-ray diffraction (XRD) patterns for the same samples of infrared spectra were measured to get information on their phases on uranium oxides (UO x) with increasing x. The measured characteristic bands from UO x samples could be assigned well by referring to the spectra reported in the literature and comparing with the diffraction patterns measured. The relationship between absorbance and O/U ratio (x) was determined. We discussed about using it for the O/U ratio estimation of uranium oxides of unknown composition. It was confirmed that ATR technology for infrared spectroscopy can be useful for the studies of radioactive materials that are difficult to handle using conventional methods.

“…Its complex structure has been previously studied by several models including those of Loopstra (using neutron diffraction [30]) and Ohwada and Soga with approximate coordination analysis [31] to an ever-complicated array of vibrational assignments that is as yet not complete. Butler et al have endeavored to complement theoretical calculations using the models of Loopstra and Ohwada with experimental Raman spectra [20].…”
