Depolarized fight scattering

Depolarized Scattering and Rotational Diffusion Most flexible and semiflexible polymers are isotropic and hence do not depolarize incident polarized light. For particles with shape anisotropy there will be a tensor polarizability and the scattered fight will have depolarized components. Depolarized scattering principles and nomenclature are covered in Sections 8.1,8.2.4, and 8.4. [Pg.91]

Besides translational diffusion, anisotropic particles can also undergo rotational diffusion. A rodlike particle has a rotational diffusion coefficient, 0, which can be measured from the autocorrelation function for depolarized scattered fight for example, by placing an analyzing polarizer at right angles to the incident electric field polarization in front of a detector in the scattering plane (which is perpendicular to the incident polarization direction).
