We study the stability of the molecular structure of DOBAMBC, a prototype of ferrolectric liquid crystal, using the linear stability analisys for Hamiltonian systems. We show the existence of thermodynamically stable states in a narrow temperature region between the A - phase and the ordinary smectic - C* phase.
Key words: Ferroelectric Liquid Crystals.
