WebInfrared, or IR, spectroscopy is a chemical analysis technique that takes advantage of the interaction between infrared light and matter. Infrared light is part of the electromagnetic spectrum between visible light and … Web2. Hydrogen bonds analysis of natural celluloses by using FTIR A hydrogen bond is the attractive interaction of a hydrogen atom wi th an electronegative atom, such as nitrogen, oxygen or fluorine, that comes from another molecule or chemical group. Cellulose occurs in the form of long, slender chains, polymer of 1-4 linked Ã-D-glucose (Figure 1).
