The minerals are characterised by well-defined hydroxyl stretching patterns, which give two groups of hydrogen bonds with calculated hydrogen bond distances of 2.90 and 2.84–7 A.
Alunite Supergroup: Mineral information, data and localities.
Also known as Alunite Family or Alunite Group. This supergroup includes: Alunite Group, Beudantite Group, Plumbogummite Group and Dussertite Group. Various other names have been used for these groups (see Mills et al. 2009; Bayliss et al. 2010). Crystals in theRAMAN AND IR SPECTROSCOPIC STUDIES OF,4 and M–O peaks of the alunite-group phases, and Cr-, Fe- and V-based analogues with substitution of K, Na or H 3O at the A site in the Raman and IR spectra. Raman and IR spectroscopies are therefore useful in distinguishing these compounds.
