Description

The presence of hydroxyl ions has been detected in as-grown KHo(WO4)2 double tungstate single crystals by Fourier Transform Infrared (FTIR) spectroscopy. The absorption bands of the stretching vibration of OH- ions have been observed between 8-300 K in the 3450-3650 cm-1 wave number range. The temperature and polarization dependences of several intense narrow absorption lines corresponding to hydroxyl ions in different environments have been studied in detail. All lines were shifted, broadened and their intensity was decreased by increasing temperature due to phonon coupling. The band intensities strongly depended on the light propagation and polarization directions, allowing the determination of the orientation of OH- dipoles with respect to the crystallographic axes. The isotopic replicas of several OH- bands have been detected between 2550-2650 cm-1 in crystals treated in D2O water vapour at 873 K. (copyright 2005 WILEY-VCH Verlag GmbH and Co.
