Abstract
Solid state proton magnetic resonance spectra were measured for the binary system of dioctadecyldimethylammonium chloride and water in different phases and at different compositions. From the lineshape and relaxation measurements it was shown that water in each phase consisted of multicomponents. In particular, the existence of intermediate water detected by thermal analyses was proved. NMR data also provided information on the dynamic behavior of water. The motion of the intermediate water in the gel phase was remarkable. By analysis of the split 1H NMR pattern due to dipole coupling and quadrupole splitting in the deuterium magnetic resonance spectra, an image of the motion of the intermediate water could be obtained.
