Abstract : We determine viscosity values of ZLI-2293 Merck, to our knowledge for the first time, from a measured transmission versus time curve of a TN-cell with the -optical bounce- 1, 2. Our method combines the measurement of this transmission curve with the simulation of the corresponding director field and a suitable optimization process using Simulated Annealing 3 to obtain the viscosities. The advantage of our approach is the small experimental expense compared to that of a direct viscosimetric measurement while achieving nearly the accuracy of the direct method.
