Raman spectroscopic study of the uranyl mineral compreignacite K2[(UO2)3O2(OH)3]2.7H2O
Raman spectra of the uranyl oxyhydroxy hydrated mineral compreignacite, K2[(UO2)3O2(OH)3]2.7H2O, were measured and interpreted. Observed bands were attributed to the stretching and bending vibrations of uranyl units, molecular water and hydroxyl ions. U-O bond lengths in uranyl and O-H…O hydrogen bond lengths were inferred from the spectra and compared with those from the X-ray single crystal structure data. The importance of this spectroscopic study rests with the ability to analyze very small amounts of mineral.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloads displays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
