Zusammenfassung: 
The presence of hydrogen defects in ABO(3) crystals is revealed by a characteristic OH stretching vibration near 3500 cm(-1). Recently we reported about combination absorption bands of the libration with the vibration of the OH oscillator observed for the first time in several ABO(3) crystals. Direct librational modes have not been reported so far for these crystals. In proton exchanged (PE) surface layers of LiNbO3 with a very high OH concentration the direct OH librational mode at 960 cm(-1) is observed by Raman scattering. The observed OH librational wavenumber is in agreement with a description of the libration by a simple harmonic oscillator model.
