Beginning with a thermodynamic description of the state of water in heterogeneous "microosmotic" systems, a multistate theory of water activity is presented together with theoretical relationships between NMR water relaxation times, water activity and electrical conductivity. These relationships are
Magic-angle spinning (MAS) 2 H and 17 O NMR spectra were obtained for water, following addition to an activated carbon. Shortly after addition two peaks are seen: a 'free liquid' resonance and a second broad resonance shifted to low frequency. The latter is attributed to water in the pores of the ac
