Descrição: dc.descriptionWe have studied the borate mineral szaibelyite MgBO2(OH) using electron microscopy and vibrational spectroscopy. EDS spectra show a phase composed of Mg with minor amounts of Fe. Both tetrahedral and trigonal boron units are observed. The nominal resolution of the Raman spectrometer is of the order of 2 cm 1 and as such is sufficient enough to identify separate bands for the stretching bands of the two boron isotopes. The Raman band at 1099 cm 1 with a shoulder band at 1093 cm 1 is assigned to BO stretching vibration. Raman bands at 1144, 1157, 1229, 1318 cm 1 are attributed to the BOH in-plane bending modes. Raman bands at 836 and 988 cm 1 are attributed to the antisymmetric stretching modes of tetrahedral boron. The infrared bands at 3559 and 3547 cm 1 are assigned to hydroxyl stretching vibrations. Broad infrared bands at 3269 and 3398 cm 1 are assigned to water stretching vibrations. Infrared bands at 1306, 1352, 1391, 1437 cm 1 are assigned to the antisymmetric stretching vibrations of trigonal boron. Vibrational spectroscopy enables aspects of the molecular structure of the borate mineral szaibelyite to be assessed.-
