摘要
In relaxation experiments in aqueous micellar solutions one observes two processes. In order to compare the kinetic data obtained by different methods, these processes were investigated unsing p-jump and stopped-flow as perturbation methods, and conductivity and extinction as detection methods. The agreement is suffcient. The results for the amplitudes measured in stopped-flow experiments indicate that with ionic surfactans the number density of monomers does not remain constant above the cmc, but decreases again with increasing surfactant concentration. The consideration of this fact leads to a qualitative agreement between theory and experiment.
