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.
Thermal stabilities of americium and cerium tetrafluorides

The thermal stabilities of americium and cerium tetrafluorides were determined by mass spectrometry, monitoring their gaseous vaporization and/or decomposition products as a function of temperature. For americium tetrafluoride, the dominant high temperature (less than or equal to 700°C) process is thermal decomposition to the trifluoride. In contrast, with cerium tetrafluoride, the most prominent process at high temperature (less than or equal to 850°C) is congruent sublimation. The results of these studies are interpreted in terms of the relevant thermodynamic parameters for each process and are compared with predictions and results which have been reported in the literature.
