Sažetak
The change of the electric birefringence is investigated when is applying alternating electric field on a thin film (thickness d = 3·10⁻⁵ m) of the TNC-1285 nematic phase, production of “Merck”–W. Germany. The investigation has been taken in nematic phase, for three temperatures. From the measurements are obtained the optical contrast and the rise and decay times of the molecules of the liquid crystal. Elastic splay constant K₁₁ is calculated by means of decay and rise times for temperatures T = 295.8 K; T = 309.2 K.
