WebThe carbonyl stretching absorption is one of the strongest IR absorptions, and is very useful in structure determination as one can determine both the number of carbonyl groups … WebApr 8, 2024 · The chemical structure of the Fe 3 O 4 /PIn particles was confirmed based on FTIR spectroscopy. The spectra of Fe 3 O 4 and PIn particles were also examined to determine the extent of particle coating. In particular, the spectra of Fe 3 O 4 spheres presented several characteristic peaks, such as that corresponding to the stretching of …
