NMR and monte carlo simulation studies of water adsorption dynamics.
Nuclear magnetic resonance water proton spin-spin relaxation time T(2) 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 tau for reorientation of the water molecule proton-proton vectors. We demonstrate that 1/T(2) and tau 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.
