Raman Scattering and Fluorescence Polarization

Ordinary methods of polarimetry, such as birefringence and dichroism, provide information about the second moment of the orientation distribution of the microstructural elements [Pg.43]

Polarized fluorescence arises from a different optical interaction with matter than does Raman scattering, but as in Raman scattering, the wavelength of the emitted light differs from that of the incident light. Also like Raman scattering, fluorescence polarization also allows one to measure both second and fourth moments of the orientation of specific bonds in a molecule. Monnerie (1987) has pioneered the application of fluorescence polarization methods to polymer dynamics. [Pg.44]
