  3. Proton magnetic resonance of wood and water in wood

    Araujo, Cynthia D.University of British Columbia1993

    Proton nuclear magnetic resonance (11-1 NMR ) was used to investigate protons in solid wood and compartmentalized water in the wood cell walls and lumens. A lineshape second moment study found the second moment of protons in oven dry wood to be about 23% lower than the rigid lattice calculation, …
