Abstract Infrared and Raman spectra of YNbO4 and YTaO4 are reported. These spectra show the internal vibrational modes of the NbO3−4 and TaO3−4 tetrahedra which occur seldom in solids. The ν3 mode is situated at low wavenumbers relative to ν1. This corresponds to low values of the force constants in the OVFF model.
