This volume is a new follow-up volume that complements Dynamic Light Scattering (1993) by the same author. The volume is directed to the recent development in the light scattering technique and to describing a wide spectrum of its applications. Both the theoretical development and utilization are traced by authors who are expert in their fields. Development in static light scattering as applied to simple liquids, polymer solutions, and multi-component polymer mixtures are dealt with. The scattering theory of colloidal dispersions is described and scattering from rod-like polyelectolytes is reviewed. There are chapters on concentrated polymer systems, aggregation phenomena, polymer-polymer interactions, polyelectrolytes in solution. Emphasis is given to more complex systems, for example, ternary polymer systems, complex micellar systems, and block copolymers in the ordered and disordered states. Low-angle light scattering is reviewed, as well as simultaneous static and dynamic light scattering. The determination of particle size distributions and combined chromatographic light scattering techniques are also treated.

Dynamic light scattering is a new method for investigating macromolecular systems. The importance of the technique lies in its non-invasive character. It can be employed on extremely small fluid volumes, the instrumentation is relatively inexpensive and allows the rapid determination of diffusion coefficients as well as providing information on relaxation time distributions for the macromolecular components of complex systems.This volume is directed in part to the philosophy and current practice in dynamic light scattering: single photon correlation techniques are introduced, a discussion of noise on photon correlation functions is given and data analysis in dynamic light scattering to polymer structure analysis is presented and a comprehensive introduction to diffusing wave spectroscopy is given. Theoretical developments relating dynamic light scattering to the viscoelasticity of polymers in solution and in the bulk are described. The second aim is to illustrate the widely varying fields in which the technique finds application. Chapters are to be found on multicomponent mixtures, polyelectrolytes, dense polymer systems, gels, rigid rods, micellar systems and the application of dynamic light scattering to biological systems.

The application of selected scattering methods, in particular light and neutron scattering, to complex polymeric and colloidal systems is discussed. Progress in this area of condensed matter is charted and the book provides insight into the theory and practice of the techniques apploed to a number of diverse problems.
