Abstract
Spectra of light scattered from MBBA in the nematic phase near the convective instability point are measured using a quasi-elastic light scattering technique. It is observed that, in the polarized scattering one of coupling modes among the viscous made, the relaxation mode of a space charge and the combinational mode of “splay” and “bending” shows a critical slowing down at the instability threshold, while in the depolarized scattering the observed mode is independent of an electric field. The angular dependence of these modes also is measured. These results are found to be in agreement with recent theoretical predictions.
