Abstract
The real and the imaginary parts of the shear mechanical impedance were measured at 15 MHz near the smectic-A to smectic-B phase transition in N-(p-butoxybenzylidene)-p-n-octylaniline, for shear waves propagating along the normal to the layers. In both phases the shear reponse presents large relaxation effects. A pretransitional behavior in the real part of the shear impedance is found in a temperature interval of ~ 2°C below the transition.
