WebA.A. Refaat, in Comprehensive Renewable Energy, 2012 5.13.4.4.1 Cellulose crystallinity (crystallinity index, CrI). The degree of crystallinity of cellulose is expressed in terms of the crystallinity index (CrI); this is determined by the ratio of the crystalline peak to valley (amorphous region) in the diffractogram based on a monoclinic structure of cellulose [175].

Cellulose crystallites are thought to be imperfect, and thus a significant portion of the cellulose structure is less ordered; this portion is often referred to as amorphous. A parameter termed the crystallinity index (CI) has been used to describe the relative amount of crystalline material in cellulose.
