This talk will briefly review principles and data interpretations of infrared, Raman, and sum frequency generation (SFG) vibrational spectroscopy for analysis of cellulose in the isolated and purified form as well as in the native form inside plant cell walls. It will cover the vibrational modes of crystalline celluloses, how the chain orientation in crystalline domain is analyzed in each method, and how the concentration and spatial distribution of crystalline cellulose domains interspersed in amorphous matrices are manifested or analyzed differently in these three methods. Lastly, a few examples of IR, Raman, and SFG including spectroscopic imaging will be presented for analysis of crystalline cellulose in plant cell walls or lignocellulose biomass.
