Relation of certain infrared bands to cellulose crystallinity and crystal lattice type. Part II. A new infrared ratio for estimation of crystallinity in celluloses I and II
TL;DR: In this paper, a new infrared ratio, α1372 cm.−1/α2900 cm−1, is proposed for measuring crystallinity in cellulosic materials, which can be applied to both celluloses I and II and, therefore, to samples containing a mixed lattice.
