title: Vibrational spectra and factor group analysis of M₀.₅₀TiOPO₄ oxyphosphates (M=Mg, Zn, Ni, Co, Fe and Cu).
abstract: Raman spectra of a series of orthophosphates M(0.50)TiO(PO(4)) (M=Mg, Zn, Ni, Co, Fe, and Cu) have been recorded in crystalline state. Factor group analysis has been performed for space group P2(1)/c and assignments of the internal modes of the [PO(4)] tetrahedra and [TiO(6)] octahedra have been made.
