Theory of dynamic light scattering from polydisperse systems
Abstract
Analytical expressions for the light scattering autocorrelation function of Schulz distributed Rayleigh–Debye particles are presented. The theory is shown to be valid for spheres, thin rods, disks, and Gaussian coils executing translational diffusion. The polydisperse form factors for these shapes are also given. Analysis of polydisperse data with the expressions given yields the diffusion coefficient of the number average species and the Schulz polydispersity parameter. The effects of polydispersity on the angular dependence of the decay time and the conditions under which the form factor can be neglected are discussed.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
