This book should be of interest to researchers in physics, physical chemistry, biophysics and medical biophysics.

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 second aim is to illustrate the widely varying fields in which the technique finds application. Theoretical developments relating dynamic light scattering to the viscoelasticity of polymers in solution and in the bulk are described. 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. 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. The importance of the technique lies in its non-invasive character.
