Raman spectroscopy of the minerals boleite, cumengeite, diaboleite and phosgenite –implications for the analysis of cosmetics of antiquity
Frost, Ray L., Martens, Wayde N., & Williams, Peter A. (2003) Raman spectroscopy of the minerals boleite, cumengeite, diaboleite and phosgenite –implications for the analysis of cosmetics of antiquity. Mineralogical Magazine, 61(1), pp. 103-111.
The application of Raman spectroscopy to the study of the mixed cationic lead-copper and lead-copper-silver minerals: boleite, cumengeite, diaboleite has enabled their molecular structure to be compared. Each of these three minerals shows different hydroxyl-stretching vibrational patterns, but some similarity exists in the Raman spectra of the hydroxyl deformation modes. The low wavenumber region is characterised by the bands assigned to the cation-chloride stretching and bending modes. Phosgenite is also a mixed chloride-carbonate mineral and a comparison is made with the molecular structure of the aforementioned minerals. Raman spectroscopy lends itself to the study of these types of minerals in complex mineral systems of secondary mineral formation.
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.
