A pulsed NMR study of structural ordering in water-oil emulsions

Pulsed NMR techniques were used to conduct a structural-dynamic analysis of water-oil emulsions based on the temperature dependence of relaxation time s of water and oil protons and the dependence of relaxation times on the pu lse frequency in the Karr-Parcell-Meiboom-Gill sequence. Correlation times, activation energies, and exchange lifetimes were determined. The conclusio n was drawn that structural ordering occurred in emulsions at interfaces.
