The arsenate hydroxyl-bearing minerals sarkinite and adamite were studied with vibrational spectroscopic (IR and Raman) and quantum theoretical methods. The observed IR bands in the higher (1100–600cm −1 ) and especially lower (600–450cm −1 ) frequency region of AsO 4 vibrations could clearly discriminate between the studied analogues. The differences between their crystal...
Endemic mineral nežilovite was studied by vibrational spectroscopy (IR and Raman), quantum theoretical methods and X-ray powder diffraction. Experimental Raman as well as the higher-frequency region of the infrared spectra of this mineral closely resembles to the corresponding spectra of magnetoplumbite-group minerals, while the appearance of the lower-frequency part of the IR spectra is markedly...
