Abstract: By comparing three pulse sequences STE LED LED-BPP, one is selected, which is the best to measure the self-diffosion coefficient of surfactant solution, in which there exists coupling effect. Self-diffusion coefficients of a series of sodium dodecyl sulfonate D2O and D2O-NaCl solutions with different concentrations were measured. The aggregation behavior of this surfactant in aqueous solution is thus deduced.

Key words: Sodium dodecyl sulfonate, Self-diffusion coefficient, Stimulated echo, LED, LED-BPP
