Pretransitional Light Scattering Studies

There are other reports on the study of pretransitional dynamics in polymeric and lyotropic nematics. Quantitative measurements of ratios of Frank elastic constants and Leslie viscosities in the pretransitional range of poly-y-benzyl-glutamate polymeric nematic are reported by Taratuta et al. [85]. McClymer and Keyes [86-88] report light scattering studies of pretransitional dynamics of potassium laurate-decanol-D20 system. An interesting study of a magnetic-field induced I N phase transition in a colloidal suspension is reported by Tang and Fraden [89]. [Pg.1157]

Light scattering is a probe of molecular motions, and may be used effectively to study pretransitional phenomena. Stintson et al. [123] studied light scattered by order parameter fluctuations in MBBA. Their data follow the relationship ... [Pg.745]
