Abstract

Nuclear magnetic resonance water proton spin–spin relaxation time T2 was measured in wood samples with moisture contents ranging from 0.50 to 26.4%. The experimental results are discussed in terms of Monte Carlo simulations, which determine the correlation times τ for reorientation of the water molecule proton–proton vectors. We demonstrate that 1/T2 and τ qualitatively follow the same behavior with surface hydration. The common application of the multisite exchange model to hydrated systems is discussed in light of the new results.
