Raman spectroscopic study of the uranyl selenite mineral marthozite Cu[(UO2)3(SeO3)2O2].8H2O
Frost, Ray L., Cejka, Jiri, Keeffe, Eloise C., & Dickfos, Marilla J. (2008) Raman spectroscopic study of the uranyl selenite mineral marthozite Cu[(UO2)3(SeO3)2O2].8H2O. Journal of Raman Spectroscopy, 39(10), pp. 1413-1418.
The mineral marthozite, a uranyl selenite, has been characterised by Raman spectroscopy at 298 K. The bands at 812 and 797 cm-1 were assigned to the symmetric stretching modes of the (UO2)2+ and (SeO3)2- units, respectively. These values gave calculated U-O bond lengths in uranyl of 1.799 and/or 1.814 Å. Average U-O bond length in uranyl is 1.795 Å, inferred from the X-ray single crystal structure analysis of marthozite by Cooper and Hawthorne. The broad band at 869 cm-1 was assigned to the ν3 antisymmetric stretching mode of the (UO2)2+ (calculated U-O bond length 1.808 Å). The band at 739 cm-1 was attributed to the ν3 antisymmetric stretching vibration of the (SeO3)2- units. The ν4 and the ν2 vibrational modes of the (SeO3)2- units were observed at 424 cm-1 and 473 cm-1. Bands observed at 257, and 199 and 139 cm-1 were assigned to OUO bending vibrations and lattice vibrations, respectively. O-H..O hydrogen bond lengths were inferred using the Libowiztky's empirical relation. The infrared spectrum of marthozite was studied for complementation.
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.
