Abstract
NMR spectra of water molecules sorbed into polymers were measured by the 1H and 2H NMR procedures. The resonance peak width (Δν1/2) and spin-lattice relaxation time (T1) of 2H2O NMR spectra, which reflect the molecular motion of sorbed water, were found to vary according to the polymer chemical structures. Their variations originate from the differences in the heat (ΔE) of water sorption into polymers due to the polymer chemical structures.
