Micro-Raman spectroscopy of natural members along CuSbS2-CuSbSe2 join
Popis výsledku v původním jazyce
Micro-Raman spectroscopy was used to investigate the natural orthorhombic members (space group Pnma) along the CuSbS2-CuSbSe2 join: chalcostibite Cu1.01Sb1.00S1.99 from Dubrava (Slovak Republic); Se-rich chalcostibite Cu-1.00(Sb0.99As0.02)(1.01)(S1.29Se0.70)(1.99) and the new mineral příbramite Cu-0.99(Sb1.03As0.01)(1.04)(Se1.82S0.15)(1.97) both from the Příbram uranium and base-metal district (Czech Republic). Stretching and bending vibrations of the pyramidal SbS3 groups occur between 350 and 200cm(-1); vibrations of SbSe3 groups are shifted to the range 240-80cm(-1) due to the almost twice heavier mass of Se compared with S. The shift of the (1) symmetric Sb-(S,Se) vibration was observed, yielding 113cm(-1), and for the (3) antisymmetric stretching Sb-(S,Se), vibration was about 127cm(-1). The wavenumber of the (1) symmetric Sb-S stretching vibrations decreases with increasing Se contentfrom 336 (in chalcostibite) over 330 (in Se-rich chalcostibite) to 326cm(-1) (in příbramite), and a similar situation was observed for the case of (1) symmetric Sb-Se stretching vibrations from 220 in Se-rich chalcostibite to 215cm(-1) in příbramite. The trend for the (3) antisymmetric Sb-(S,Se) stretching vibrations is the opposite, from 306cm(-1) in chalcostibite to 314cm(-1) in Se-rich chalcostibite (Sb-S bonds) and from 180cm(-1) in Se-rich chalcostibite to 185cm(-1) in příbramite (Sb-Se bonds). These small shifts are probably connected with the influencing of the bonding environment of SbS3 and SbSe3 pyramids. The vibrations of Cu-S(Se) bonds are represented only by less intense bands, and the observed intense bands below 80cm(-1) should correspond to external modes.
