It has been reported that if a shear flow is applied to the nematic phase of 8CB, some dynamical structure are induced. To clarify these structures is more detail, transient dielectric response after the application of the shear flow was measured. In the flow alignment region the dielectric permittivity decreased monotonously, while in the precession region a damped-oscillation of the dielectric permittivity was measured with critical increases in the oscillating frequency and damping faster when approaching to the nematic to smectic A phase transition point. These results will be discussed based on the fluctuation of smectic A structure.
