Raman spectra of selected transuranium trihalides in the solid state
摘要:
Raman spectral data have been obtained from a number of transuranium trihalides in the solid state. The Raman spectra of these actinide compounds are reported and compared to the published Raman spectra of isostructural compounds. Tentative symmetry assignments have been made for the observed Raman-active lattice vibrations based on nuclear site symmetry analysis of their respective crystal structures and comparisons to the symmetry assignments made for isostructural lanthanide compounds. The Raman spectral data obtained in this study represent a partial data base for the use of Raman spectroscopy for identifying the crystal structures exhibited by these and isostructural compounds.

CmCl3 has been found to exhibit the hexagonal UCl3 structure. Powder data from two samples give average latticeparameters a = 7·380 ± 0·006 Å and c = 4·186 ± 0·010 Å, where the error limits are the 95 per cent confidence interval calculated using the standard statistical method for the average of two independent determinations.
