Abstract
We have studied the reorientational dynamics of neat biphenyl (BP) and pentylcyanobiphenyl (5CB) as well as solutions of these compounds in n-heptane over an extended temperature range with a polarization selective transient grating (TG) optical Kerr effect (OKE) approach. Whereas neat BP and the solution samples show a behavior typical for a simple liquid and hydrodynamic models, the dynamics of neat 5CB (in the isotropic phase) is dominated by the specific liquid structure.KeywordsBulk ViscosityIsotropic PhaseRotational DynamicOptical Kerr EffectTransient GratingThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
