Aggregation kinetics and aggregate structure are studied for monodisperse polystyrene latex particles of diameter 60 and 140 nm. The experimental part consists of measurements over a rather broad range of electrolyte concentrations (0.1 to 0.8 M NaCl) and for particle volume fractions 10(-6) to 10(-
Polarized dynamic light-scattering measurements on superhelical pBR322-plasmid DNA solutions in 0.2M NaC1,2 mM NaPi, pH 7.0,2 mM EDTA result in a translational diffusion coefficient D$, , . c = (3.77 f 0.10) X cmz/s for the native molecule. Modeling the DNA, in the simplest approximation, as a 10 X
## Abstract This paper deals with the light scattering from particles rotating in a flow with a transverse velocity gradient. It is theoretically substantiated and experimentally proved that the scattered light spectrum contains reliable information of the particle configuration and dimensions. The
