Abstract: Theoretical and experimental research into the dynamic and correlation properties of smectic liquid-crystal films is reviewed. Both freely suspended films and films fastened to a solid substrate are considered. For smectic-A films, the intensity of X-ray scattering and the temporal correlation function of scattering intensities are analyzed. For smectics with the director tilted with respect to the layers, the intensity of scattering light is discussed. To illustrate theoretical results, available experimental data are used.
