Spectroscopic and bond-topological investigation of interstitial volatiles in beryl from Slovakia

Popis výsledku v původním jazyce

Nine beryl samples from Western Carpathians, Slovakia, were investigated by infrared and Raman spectroscopy and differential thermal analysis. Two types of water H2O I and H2O II were detected. Infrared spectroscopy proved the presence of water type I and II in the presence of alkali cations with several bands: (1) symmetric stretching vibration-nu(1); (2) antisymmetric stretching mode-nu(3); (3) bending vibration-nu(2). The presence of singly and doubly coordinated type II water (IIs and IId) was confirmed by single-crystal IR spectroscopy. From Raman spectra a band at 3606 cm(-1) was assigned to nu(1) of water type I and the range of 3597-3600 cm(-1) to water type II. The presence of doubly coordinating water indicates a relatively highly hydrated environment with the presence of alkali ions including Na as the dominant cation coordinated by H2O II. CO2 bands were detected only by single-crystal IR spectroscopy. Thermal analysis proved total water loss in the range of 1.4-2.
