WebApr 15, 2024 · Based on the FT-IR spectra of tannins and germanium–tannins , the diffraction peak near 3400 cm −1 becomes wider and the peak strength weakens, which is mainly due to the reduction of the chemical bond force constant K when the hydroxyl group forms a new intramolecular hydrogen bond, and the stretching vibration absorption peak … WebThe size is peak area. It is used to determine the functional groups qualitatively and quantitatively. Basically IR peaks are the result of dipole radiation interactions for a …

WebMay 1, 2024 · For saturated ethers there is one C-C-O asymmetric stretch from 1140 to 1070, for mixed ethers there are two of these peaks at 1300–1200 and 1050–1010, and for aryl ethers there is one peak that falls from 1300 to 1200. When a methyl group is attached to an ether oxygen it is called a methoxy group. WebPeak around 3000 − 3100 cm - 1 for the sp A 2 = C − H stretch and peak at around 1670 cm-1 corresponding to the carbonyl sp A 2 C = C stretching. So the compound has an alkenic group. The other peaks are for C-C and C-H single bonds. Therefore, The IR thus supports presence of alkenic double bond.
