FTIR Basic Organic Functional Group Reference Chart (PDF) Functional groups are structural units within organic compounds defined by specific atom and bond arrangements. Infrared is a powerful identification tool for functional groups because of the similar absorption frequencies for those groups in di...
functional areas (4000 - 1300cm-1) and fingerprint areas (1300 - 600cm-1). The characteristic absorption peak of the group usually appears in the functional group, and the absorption peak is sparse, which is beneficial to the analysis, and is the most useful area for the identification of...
Both techniques provide organic compound identification; and are not limited simply to functional group identification. The minimum spot size in Raman is 1 µm, significantly smaller than for FTIR. Certain samples analyzed by Raman will show interference from fluorescence. Also, in Raman spectroscopy...
Fourier transform infrared spectroscopy (FTIR), as a non-destructive method, is widely used for the identification of compounds and the characterization of molecular structures. In order to characterize the changes in the chemical structure of charcoal under different combustion temperatur...

These types of absorbances are typically seen below 1500cm-1 in the infrared spectrum; however, some functional groups will absorb in this region as well. As a result, this region of the spectrum is less reliable for identification, but the absence of a band is often more indicative than...

Rep., 13 (2023), Article 14716, 10.1038/s41598-023-42086-1 Google Scholar Cited by (1) Evaluation of minced beef quality fortified with edible microalgae species during...
The identification of these compounds was done by carefully identifying the Cr-O-Cr anti-symmetric vibrations, the symmetric stretching of the CrO4 tetrahedra, and the stretching vibrations of the planar CrO3 structure for the chromium trioxide. All the above compounds were volatile, and present as...
The characteristic absorption peak of the group usually appears in the functional group, and the absorption peak is sparse, which is beneficial to the analysis, and is the most useful area for the identification of the group. The latter mainly contains spectra produced by deformation vibration. ...
