Structural and Temperature-dependent vibrational analyses of the non-centrosymmetric ZnMoO4 molybdate

The triclinic phase of zinc molybdate znmoo4 was synthesized by a simple co-precipitation method followed by calcination at different temperatures. thermal differential and thermogravimetry analyses were performed under air. the polycrystalline samples of znmoo4 compound obtained with different thermal treatments were characterized by x-ray diffraction,cell parameters were determined using lebail fit analyses and the crystallites size was calculated using scherrer equation. fourier transform infrared and raman spectroscopy analyses were investigated and discussed,all the bands were assigned the corresponding vibrations. correlation with structural and thermal analyses was made.
