Novel Approaches Using FTIR Spectroscopy to Study the Structure of Crystalline and Noncrystalline Cellulose

This paper deals with introduction of two methods with combination of FTIR which are very powerful to investigate cellulose supermolecular structures. One is using a microscopic accessary and the other is using a special reaction cell for deuteration. The former method depends on interpretation of change of the characteristic IR bands for cellulose Iα and Iβ crystalline phases to determine crystalline structures during coniferous wood cell wall formation, while the latter needs kinetic approaches to characterize amorphous structures by monitoring changes of OH bands during the deuteration process with D₂O as a probe for amorphous 3 film samples, cellulose, 2,3-di-O-methylcellulose (23MC) and 6-O-methylcellulose (6MC).
