Example of the fit analysis of field autocorrelation function g1(k,τ) measured for a system composed of a water solution of amphiphilic modified cyclodextrin (CD). Double exponential fit of the g1(k,τ) function for the system CD4 [163] (A), and analysis of the relaxation time distribution τA(τ) as a function of the hydrodynamic radius RH obtained by the inverse Laplace transformation with regularized positive exponential sum REPES approach (inset of A). Triple exponential fit of the g1(k,τ) function for the system CD3 (A) [163], and the REPES analysis, which evidence the presence of three populations of scattering particles (namely unimers, micelles and vesicels) (B).
