WebMay 29, 2024 · The first overtones of the asymmetric and symmetric CH 2 stretching modes occur respectively at 5900 and 5775 cm −1, whereas the combination bands ν (OH) + δ (OH) and 1st overtone ν (C-O) amide I + amide II are visible near 5160 and 4600 cm −1 respectively [ 1 ]. WebA band shift of the first overtone occurs for XH bands due to a hydrogen bond and an interaction between molecules as in the case of an IR spectrum. The shift is much bigger than that of the corresponding IR band. 5. In the NIR region, OH and NH stretching bands of monomeric and polymeric species are better separated compared with the IR region.
