5 Electric Field-Induced Orientation and Relaxation of Liquid-Crystalline Systems [Pg.38]

The reorientation of liquid crystals in an external electric field is the basis of their technical application in liquid-crystal displays (LCDs) and has been treated in numerous books and reviews [1-3, 12, 38, 46 50]. This section is intended to demonstrate the application of time-resolved FTIR spectroscopy for a better understanding of the electro-optical performance of liquid-crystalline systems. Due to the reversible character of the orientational and relaxational motions of liquid crystals under the perturbation of an electric field, the time-resolution of the FTIR measurements can be extended down to the microsecond range by the implementation of the step-scan technique (see Section 2.2). Thus, an insight on a molecular level [Pg.38]
