Synthesis and Raman spectroscopic characterisation of the oxalate mineral wheatleyite Na2Cu2+(C2O4)2.2H2O
Frost, Ray L., Locke, Ashley J., & Martens, Wayde N. (2008) Synthesis and Raman spectroscopic characterisation of the oxalate mineral wheatleyite Na2Cu2+(C2O4)2.2H2O. Journal of Raman Spectroscopy, 39(7), pp. 901-908.
The mineral wheatleyite was synthesised and characterised by Raman spectroscopy complimented with infrared spectroscopy. Two Raman bands at 1434 and 1470 cm-1 are assigned to the ν(C-O) stretching mode and implies two independent oxalate anions.
Two intense Raman bands observed at 904 and 860 cm-1 are assigned to the ν(C-C) stretching mode and support the concept of two non-equivalent oxalate units in the wheatleyite structure. Two strong bands observed at 565 and 585 cm-1 are assigned to the symmetric CCO in plane bending modes. The Raman band at 387 cm-1 is attributed to the CuO stretching vibration and the bands at 127 and 173 cm-1 to OCuO bending vibrations. A comparison is made with Raman spectra of selected natural oxalate bearing minerals. Oxalates are markers or indicators of environmental events. Oxalates are readily determined by Raman spectroscopy. Thus deterioration of works of art, biogeochemical cycles, plant metal complexation, the presence of pigments and minerals formed in caves can be analysed.
Citation countsare sourced monthly fromand 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 downloadsdisplays 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.
