A diagrammatic representation of data on
scattering from large particles, corresponding to the equation:
and used for the simultaneous evaluation of the mass average molar mass,
, the second
virial coefficient of the
chemical potential,
, and (usually) the z-average
radius of gyration,
;
is the mass concentration of the solute,
the excess
Rayleigh ratio, and
the
particle scattering function that comprises (usually) the z-average
radius of gyration.
depends on the solute, the temperature and the type of radiation employed. Several
modifications of the Zimm plot are in frequent use; the most common one uses the excess
scattering instead of the
excess Rayleigh ratio.
