Ir peak search

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. WebIR spectroscopy is useful when it comes to analysis of inorganic compounds (such as metal complexes or fluoromanganates) as well. Category: Spectroscopy. This article is licensed …
