“…The crystals are mostly composed of several parallel intergrown individuals, but some are well defined prisms with simple pinacoidal terminations; doubly terminated prisms occur rarely. The X-ray powder pattern agreed with published data for chalcomenite (Mandarino, 1964;PDF 17-523), and the distinctive infrared absorption spectrum matched that of synthetic chalcomenite (Makatun et al, 1970). Only copper and selenium were detected by energydispersive electron microprobe analysis.…”

“…No minerals with the selenate ion SeO 4 2− have been discovered and reported. The infrared spectra of CuSeO 3 · 2H 2 O have been reported by Sathianandan et al [20] and Makatun et al [21] Farmer reports that the band positions of selenates are readily distinguished from that of selenites. The selenite ion should show a maximum of six bands.…”

Raman spectroscopy has been used to study the selenite mineral ahlfeldite. A comparison is made with the Raman spectra of chalcomenite, cobaltomenite and clinochalcomenite. Selenite minerals are characterised by the position of the symmetric stretching mode which is observed at higher wavenumbers than the anti-symmetric stretching mode. The selenite ion has C 3v symmetry and four modes, 2A 1 and 2E. These modes are observed at 813, 472 cm −1 (A 1 ) and 685, 710, 727 and 367 and 396 cm −1 (E). Bands assigned to the water stretching vibrations are observed for ahlfeldite at 3385 cm −1 , for chalcomenite at 2953, 3184 and 3506 cm −1 and for clinochalcomenite at 2909, 3193 and 3507 cm −1 . A comparison of the Raman spectra of chalcomenite, clinochalcomenite and cobaltomenite is made. The position of these bands enabled hydrogen bond distances in the selenite structure to be estimated. Hydrogen bond distances for ahlfeldite, chalcomenite and clinochalcomenite were determined to be similar.
