“…Two broad peaks at 3440 and 1630 cm −1 occur due to a small amount of absorbed water. Two absorption bands are observed at 609 and 495 cm −1 , associated with the coupling between Mn-O stretching modes of tetrahedral and octahedral sites [19,20]. Thus, the FTIR spectrum further confirms that the product is Mn 3 O 4 .…”

Heating hydrous manganese (II) hydroxide gel at 85• C for 12 hours produces Mn 3 O 4 nanoparticles. They were characterized by X-ray powder diffraction (XRD) and infrared spectroscopy (FTIR). The particle size estimated from the SEM and X -ray peak broadening is approximately 32 nm, showing them to be nanocrystalline. EPR measurements confirm a typical Mn 2+ signal with a highly resolved hyperfine structure.

“…The observed absorptions at 560 and 467 cm −1 are assigned to characteristic vibrations of metal ions in the tetrahedral or octahedral sites of the spinel structure [14,32]. [36,37] are absent in sample S 2 annealed at 1000 • C, confirming the phase purity of the final product. The analysis clearly confirms the presence of the ferrite phase and the silicon dioxide matrix.…”

“…As the bond length and force constant between atoms, and the reduced mass of the atoms or molecules present in the material can be reflected as a variation in the position and intensity of the infrared absorption bands in FTIR spectrum [38], we have performed FTIR spectroscopy in order to support our results obtained by XRD and M€ ossbauer spectroscopy. The FTIR spectra of the assynthesized samples and the samples after g-irradiation are shown in Figs.…”
