“…For this assignment, the published reflectivity and infrared spectra of proustite, pyrargyrite and ellisite [13][14][15] were used. The Raman spectra of proustite [16,17] and pyrargyrite have also been published [17][18][19]. On the other hand, the Raman spectra of ellisite and stibioellisite, to the best of our knowledge, have not been previously studied.…”

The vibrational (Raman and far infrared) spectra of four M 3 I M III S 3 type synthetic minerals (proustite, Ag 3 AsS 3 ; ellisite, Tl 3 AsS 3 ; pyrargyrite, Ag 3 SbS 3 ; stibioellisite, Tl 3 SbS 3 ) in the region from 600 to 100 cm À1 (Raman) and 600 to 20 cm À1 (far infrared) were investigated. Their infrared and Raman spectra were compared with corresponding vibrational spectra of natural orpiment, As 2 S 3 , and stibnite, Sb 2 S 3 . In general, rather expressed similarity between the Raman spectra of the M 3 I AsS 3 type synthetic minerals, and particularly between the M 3 I SbS 3 type synthetic minerals (M I ¼ Ag or Tl) was observed. This is, most probably, due to the presence of the M III S 3 pyramids (M III ¼ As or Sb) as main structural units in all minerals. The observed similarity between the Raman spectra of the M 3 I AsS 3 type minerals and the corresponding spectrum of orpiment, As 2 S 3 (also built up of M III S 3 pyramids), justifies the treatment of those pyramids as a main vibrational units. The agreement between the Raman spectra of M 3 I SbS 3 type minerals, on the one hand, and the Raman spectrum of stibnite, Sb 2 S 3 , on the other hand, is even much more pronounced. It was found, however, that the bands in the infrared spectra in the studied M 3 I M III S 3 type minerals, besides the sensitivity to the M III atom (As or Sb), are significantly influenced by the nature of the M I atom (Ag or Tl). This is most probably related to the different extent of the covalent character of the Ag-S bonds compared to the Tl-S bonds. #
