“…And each samples showed characteristics peaks of O–H stretching and H– O –H bending vibrations situated at 3420 and 1640 cm −1 , respectively.The vibrations of Mg–O, Fe–O, and Zn–O bonds at octahedral and tetrahedral sites were occurred at lower frequency regions. The FTIR results from ferrite systems, which have a broad spectrum at 400-600 cm −1 , correspond well with these findings [ [38] , [39] , [40] , [41] , [42] ]. Furthermore, the C C bending vibrations was observed at 2338 and 2934 cm −1 [ 43 ].…”
