WebMay 3, 2024 · It is known that two IR peaks around 750 and 710 cm −1 are characteristic for triclinic (Iα) and monoclinic unit (Iβ) allomorphs, respectively. The relative proportion of cellulose Iβ to Iα allomorph could be calculated by integrating the absorption bands near 710 and 750 cm −1 and the percentage of Iβ could be obtained. WebFigure 2. Group frequency and fingerprint regions of the mid-infrared spectrum. The region of the infrared spectrum from 1200 to 700 cm -1 is called the fingerprint region. This region is notable for the large number of infrared bands that are found there. Many different vibrations, including C-O, C-C and C-N single bond stretches, C-H bending ...
