Abstract

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.

Citation countsare sourced monthly from Scopus and Web of Science® 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.
