NMR Relaxation and Restricted Self-Diffusion of Water in Wood

Pp. 82-96 (15)

Victor V. Rodin


In the technological treatment of wood materials, it is important to control water-wood interactions. To measure the water self-diffusion coefficients properly in wetting/drying processes of wood, it is necessary to understand many factors affecting the experiments. For fibrous material, the diffusivities of water could be different along the fiber and in the direction of perpendicular to fiber axis. The chapter presents the data of NMR relaxation and 1-dimensional PFG NMR in studying anisotropic diffusion of water in wood.
