The infrared spectra of alkaline jute stick have been discussed and compared to that of untreated and control sample. A higher shift in the OH and lower shift in the CH stretching frequencies were observed in alkaline sample. The presence of a strong band at 1440–1430 cm −1 may be due to the coupling of COO − frequency with CH 2 deformation frequency. The CO stretching mode at 1240 cm −1 disappears on alkaline treatment with the formation of new peaks at 1265 and 1225 cm −1 . The β−glucosidic band at 895 cm −1 is shifted to 880 cm −1 with doubled intensity in alkaline jute stick.
