Abstract
We have measured the elastic ratios of two types of nematic liquid crystals: 4 methoxy 4’ azoxybenzene (N4) and p-p’ dibutyl azoxybenzene (Dibab). The experiments involved the use of a light scattering technique and analysis of the scattered light versus the scattering angle. From these measurements and the results of other investigators (De Jeu1), Prost2), Van Eck3)) we were able to extract and to discuss the coefficients of elasticity and viscosity.Keywords
