Book Description
Some seven years before Kerr's death, Larmor proposed that electric birefringence had its origin in the orientation of anisotropic molecules or elements within the apparently isotropic medium. The theory for this concept was formulated by Langevin. During the next half century, occasional measurements were made both to characterise the phenomenon and to evaluate the relevant physico-chemical parameters of pure liquids and molecular fluids. During the 1930-40 era, Staudinger and others demonstrated the existence in nature of giant molecules and colloidal particles. Since that time it has slowly but increasingly been realised that these big molecules or particles often have relatively large dipole moments, are generally anisotropic in structure and hence, in solution or suspension, give rise to significant electric birefringence signals. Furthermore, there have been three electronic innovations which have greatly eased the experimental measurement of the effect for such materials. These were the development of photomultiplier tubes for detection, of oscillo scope~ for display and of high voltage generators developing bursts or pulses of potential difference. The last mentioned enable the experi menter to study the Kerr effect not only for its amplitude but also in the time domain. The rates of molecular response to the switching of the electric field lead directly to information on the size and geo metry of the constituent molecules and particles in a dilute solution or suspension.

Book Description
The Advanced Study Institute on Molecular Electro-Optics was held on the campus of the Rensselaer Polytechnic Institute, Troy, New York, USA, from July 14 through July 24, 1980. This Advanced Study Institute was attended by sixteen invited lecturers and by forty-eight other participants. The present volume contains the texts of all of the invited lectures presented at the Institute. Although these lectures were supplemented by many animated discussions and by numerous short contributed papers, it was not possible to include these in the present volume. Molecular electro-optics is a difficult subject for research because it incorporates areas of theoretical physics such as elec tromagnetic theory and hydrodynamics of rotational diffusion, ex perimental physics such as lasers, optics, electric pulsers, and data collection via analog to digital converters and signal aver agers, and physical chemistry of macromolecules and colloids in solution (colloid science, biophysical chemistry, double layer polarization). This volume includes chapters on all of these subjects as well as introductions to magnets-optics and to elec trophoretic light scattering. The Advanced Study Institute was sponsored mainly by the North Atlantic Treaty Organization whose financial support made this meeting possible. Additional financial aid was supplied by the National Institutes of Health of the USA through their Fogarty International Center and the National Institute for Arthritis, Metabolism, and Digestive Diseases. Industrial contri buters consisted of the General Electric Company, Cober Electronics, and Malvern Scientific Corporation.

Book Description
Liquid crystals, polymers and polymer liquid crystals are soft condensed matter systems of major technological and scientific interest. An understanding of the macroscopic properties of these complex systems and of their many and interesting peculiarities at the molecular level can nowadays only be attained using computer simulations and statistical mechanical theories. Both in the Liquid Crystal and Polymer fields a considerable amount of simulation work has been done in the last few years with various classes of models at different special resolutions, ranging from atomistic to molecular and coarse-grained lattice models. Each of the two fields has developed its own set of tools and specialized procedures and the book aims to provide a state of the art review of the computer simulation studies of polymers and liquid crystals. This is of great importance in view of a potential cross-fertilization between these connected areas which is particularly apparent for a number of experimental systems like, e.g. polymer liquid crystals and anisotropic gels where the different fields necessarily merge. An effort has been made to assess the possibilities of a coherent description of the themes that have developed independently, and to compare and extend the theoretical and computational techniques put forward in the different areas.
