Abstract
The structures of a series of nickel and magnesium based hydrotalcites have been explored using Raman microscopy. These natural hydrotalcites are based upon sulphate or carbonate being the counter anion in the interlayer. Variation in the position of the sulphate stretching vibrations occurs and is mineral dependent. Raman spectroscopy shows a reduction in the symmetry of both sulphate and carbonate, which leads to the conclusion that the anions are bonded to the brucite-like hydroxyl surface and to the water in the interlayer. Water bending modes are identified in both the Raman and infrared spectra at positions greater than 1630 cm-1, indicating the water is strongly hydrogen bonded to both the interlayer anions and the hydrotalcite surface.

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.
