(a) Normalized D2O NMR signal intensity as a function of diffusion weighting for sample wormlike micellar solutions at Tdiff = 50 ms. (b) Diffusion coefficient of the proton in the bulk D2O of the surfactant solutions. Dashed lines in (a) represent mono-exponential decay (Eq. (1)). The dashed-line in part (b) corresponds to the diffusion of proton in the pure D2O (1.79×10−9 (m2/s)).
