Optical vibrational spectra are powerful indicators of solid phase U(VI) coordination chemistry. In addition, U(VI) minerals exhibit extreme chemical and structural diversity as artifacts of geochemical processes leading to ore formation. To determine the extent to which spectroscopic data permits identification of U solids with respect to chemistry and structural attributes, the Compendium of Uranium Raman and Infrared Experimental Spectra (CURIES) is being developed. CURIES is being compiled via exhaustive survey of peer-reviewed literature and databases and new spectral collection from undercharacterized materials. Through review of literature and databases, mineral species that lack spectra will be identified and obtained from museum and academic collections for analysis. Mineral samples that cannot be obtained from other sources will be synthesized, leveraging synthesis capabilities at Oak Ridge National Laboratory. Subsequently, characteristic spectroscopic features for subgroups of uranyl minerals within CURIES will be determined using multivariate statistical analyses on the basis of the underlying crystal chemistry.
