## Abstract Raman spectroscopy has been used to study the dimorphous selenite minerals chalcomenite, cobaltomenite and clinochalcomenite. Selenite minerals are characterised by the position of the symmetric stretching mode that is observed at higher wavenumbers than the anti‐symmetric stretching mo
## Abstract Tellurates are rare minerals as the tellurate anion is readily reduced to the tellurite ion. Often minerals with both tellurate and tellurite anions are found. An example of such a mineral containing tellurate and tellurite is yecoraite. Raman spectroscopy has been used to study this mi
## Abstract Tellurites may be subdivided according to formula and structure. Raman spectroscopy has been used to study sonoraite, an example of a tellurite with hydroxyl and water units in the mineral structure. The free tellurite ion will have __C__~3__v__~ symmetry and four modes, 2__A__~1~ and 2
