Abstract
The infrared and Raman spectra of uranyl bis(1,3-diphenyl-1,3-propaned ionate), uranyl bis(1,1,1-trifluoro-2,4-pentanodionate) and uranyl bis (2,4-pentanodionate) have been measured in the 1000-70 cm(-1) region. A D-2h symmetry was assumed and the assignments of the framework vibra tions were made based on a normal coordinate analysis. The results ind icate that the force constants for the U-O axial and equatorial bonds in all three complexes are of the same order of magnitude.
