The contributors to this volume study macroscopic flow properties and molecular mobility in complex liquids with high internal mobility and a highly anisotropic molecular shape. Particular attention is paid to the wide variety of experimental approaches, in theory as well as in computer simulation of these difficult but very important problems. The contributions are of interest to researchers in physics as well as in engineering and chemistry.
