Notes:
The angular distribution of scattered intensity and decay times of concentration fluctuations have been measured by means of digital photon counting and single-clipped photon correlation for solutions of Group C meningococcal polysaccharides at 31°C. The z-average diffusion coefficient 〈D〉z and its second moment 〈D2〉z have been determined from the time-dependent correlation function using the cumulant expansion technique. Very low observed values of 〈D〉z and the tremendous width of the polydispersity index, which is the z-average normalized variance, suggest a higher degree of aggregation than the monomer-dimer type self-association at finite concentrations.
