Abstract
This work shows the potentiality of the solid state nuclear magnetic resonance (ss-NMR) technique applied to characterize cellulosic materials and the possibility of analyze small amounts of starting material within reasonable experimental time using a modern equipment. The NMR analyses were performed to assess the conservation state of a material in order to plan appropriate conservative and restorative interventions. 13C {1H} Cross Polarization (CP) Magic Angle Spinning (MAS) NMR was used to identify the paper and wood components and the crystalline degree of the cellulose. Besides, in wood holocellulose/lignin ratio and the condensation degree of the lignin were determined.
