Description
Water plays an important role in the stability of minerals containing the deca and hexavanadates ions. A selection of minerals including pascoite, huemulite, barnesite, hewettite, metahewettite, hummerite has been analysed. Infrared spectroscopy combined with Raman spectroscopy has enabled the spectra of the water HOH stretching bands to be determined. The use of the Libowitzky type function allows for the estimation of hydrogen bond distances to be determined. The strength of the hydrogen bonds can be assessed by these hydrogen bond distances. An arbitrary value of 2.74 Å was used to separate the hydrogen bonds into two categories such that bond distances less than this value are considered as strong hydrogen bonds whereas hydrogen bond distances greater than this value are considered relatively weaker. Importantly infrared spectroscopy enables the estimation of hydrogen bond distances using an empirical function.
Impact and interest:
Citation counts are 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.
