Kurzfassung:
A system based on photon correlation spectroscopy has been constructed using a microcomputer to measure the spectral width of Rayleigh light scattered from nematic liquid crystals. Maps in the (α, φ, θ=0° ) space have been devised to find the most suitable scatterinu geometries for the determination of K 1 /η splay , K 2 /η twist and K 3 /η bend , where α, φ and θ specify the scattering angle and the director direction. The ratios have been obtained as a function of T NI – T for 4'-alkyl-4-cyanobiphenyls ( n =5∼8).
