โœฆ Synopsis

We present a simpie quantum mechanical derivation of the theory of light scittering from fluids and po!ymers. AU multiple scattering effects are obtained.

There has been a renewal in the theory of light scattering from fluids and polymers. In particular, the multiple scattering of light from gases and liquids, and the scattering of light from optically active solutions [I, 21.

In this note we construct a hamiltonian theory of the scattering light off of the centers of N "units". The units may be atoms or molecules in a liquid, or monomers on a polymer: In the Born-Oppenheimer approximation the interaction between the units takes place at two levels: (a) the interaction between the electrons (and nuc!ei) of each unit, and (b) the interaction between the center of the units. We consider "(a)", and do not discuss the statistical mechanical aspects of part (b).

Light scattering phase functions and asymmetry factors have been measured for a sample of fly ash and compared with Mie theory predictions. The results imply that fly ash can be treated as spherical particles under furnace conditions where they are well dispersed.
