Raman spectra of threadgoldite at 298 and 77 K are measured and interpreted fot rhe first time. Bands related the the (UO2)2+ and (PO4)3- stretching and bending vibrations are tenatively attributed together with the bands assigned to the stretching a and bending vibrations of water molucules and hydroxyls. Hydrogen bonding network and H2O and (OH)-1 libration modes are mentioned. U-O bond lengths in uranyls are calculated via empirical relations RU-O = f[○1 and ○3 (UO2)2+] Å. They are comparable to the values inferred from the single crystal structure analysis of threadgoldite.

Citation counts are 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.
