The phase transition of liquid crystal carboxylate is studied by using low-frequency internal friction method, under forced-vibration mode. A relationship between the height of the peak of internal friction and the vibration frequency is derived with a simple viscoelastical Maxwell model; it shows a nonlinear feature. The experimental result agrees with this relationship.
