Cellulose crystallinity measurement is one way to define the supramolecular structure of cellulose. However, from the vast literature on crystallinity, it’s clear that irrespective of the method used, the measurement inadequately defines the aggregated state of cellulose. Therefore, better approaches are needed. Raman spectroscopy is particularly well suited to this task because several pieces of information, beyond crystallinity, can be generated that when taken together provide a more accurate description of the aggregated state. Additionally, the information in Raman is more resolved because it comes from spectral features that represent both the aggregated and the molecular states of cellulose. Few examples will be presented to illustrate this capability.
