Summary

Time-Resolved Spectroscopy in Complex Liquids introduces current state-of-the-art techniques in the study of complex dynamical problems in liquid phases. With a unique focus on the experimental aspects applied to complex liquids, this volume provides an excellent overview into the quickly emerging field of soft-matter science. Researchers and engineers will find a comprehensive review of current non-linear spectroscopic and optical Kerr effect techniques, in addition to an in-depth look into relaxation dynamics in complex liquids. This volume offers current experimental findings in transient grating spectroscopy and their application to viscoelastic phenomena in glass-formers, dynamics of confined liquid-crystals, and a time-resolved analysis of the host-quest interactions of dye molecules in liquid-crystal matter. Time-Resolved Spectroscopy in Complex Liquids provides a cohesive introduction suitable for individuals involved in this emerging field, complete with the latest experimental procedures of complex liquids.
