“…The C–H bond of methoxy groups was noticed at a broad absorption peak at 3441.30 cm −1 ( El-Sakhawi et al., 2018 ). The absorption band at 2780.61 cm −1 was attributed to the C–H associated with alkynes and aromatics ( Ali et al., 2019 ). An absorption band at 2398.06 cm −1 was attributed to the C=O stretching vibrations of carboxylic while the steep peaks observed around 1630.29 to 1398.26 cm −1 corresponded to the C–C stretching, and C–O asymmetric stretch which might be attributed to the presence of an aromatic or olefinic compounds ( Lin et al., 2019 ).…”
