Abstract

An infrared absorption band at about 3307 cm-1 was detected and attributed to the 0→1 stretching vibrational transition of hydroxyl ions (OH-) in yttrium orthovanadate (YVO4) single crystals. The isotopic replica (OD-) was found at about 2455 cm-1 confirming the above assignment. The Morse-potential model was applied to determine the anharmonicity parameters of the hydroxyl vibration. Polarization measurements showed that the OH- dipoles lay in the plane perpendicular to the tetragonal axis. The temperature dependence of the band parameters was analyzed using the model of weakly coupled phonons.
