摘要：
Proton longitudinal relaxation rates of sodium oleate in aqueous solutions, as a function of surfactant concentration, indicate beyond the cmc (7 X 10(-4) M) a modification of micelle size and/or shape. This is confirmed by measurements of the surfactant self-diffusion coefficient. Water self-diffusion coefficients tend to show that oblate aggregates are progressively formed up to 5 X 10(-3) M, the concentration above which they remain of constant shape.
