Abstract
Three Ni silicate-bearing pimelite, nepouite and pecoraite minerals, from Australia have been investigated by UV-Vis-NIR spectroscopy to study the effect of Ni-Mg substitution. The observation of three major absorption bands at 9205-9095 cm-1, 15600-15190 cm-1 and 26550-25660 cm-1 are the characteristic features of Ni2+ in six fold coordination. The effect of cation substitution like Mg2+ for Ni2+ on band shifts in electronic and vibrational spectra enable the distinction between the Ni-bearing silicates.

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.
Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
