Description
Summary:The interpretation of micelle diffusion coefficients, especially those obtained by means of quasi-elastic light-scattering spectroscopy (QELSS), is discussed in light of theoretical work on macro-particle diffusion. The alleged discrepancy between QELSS results for D and results obtained by tagging micelles with dye arises because the experiments measure different physical parameters. Possible influences of monomer-micelle equilibria on QELSS data are examined, taking into account the distinction between those reactions which actually change the number of micelles and those reactions which only modulate the aggregation number n of individual micelles.
