stretching vibrations Explanation: While the FTIR bands at 4000–1300 cm-1 represented a functional group region, the appearance of strong absorption bands in the region of 4000–2500 cm-1 was due to stretching vibrations between hydrogen and some other atoms with a mass of 19 or less. The O–H and N–H stretching frequencies were in the 3700–2500 cm-1 region with various intensities Reference: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3483523/ |
