A diagrammatic representation of
scattering data on large particles, obtained at different angles but at the same concentration,
constructed by plotting

vs.

, or

vs.

and used for the determination of
molecular shape.

is the
excess Rayleigh ratio,

the
particle scattering function,

the
scattering angle and

the length of the
scattering vector.
