Which are the possible peaks in IR for Fe3O4 ?
the absorption peaks at 568 cm-1 belonged to the stretching vibration
mode of Fe–O bonds in Fe3O4 possessed absorption peaks presented at 1603 and 1278 cm-1 should be attached to the stretching vibrations of C = C
.
please help me to calculate H/C and O/C ratio?
