Two series of ferroelectric liquid crystalline materials, non-substituted and containing a methoxy lateral group at the aromatic ring of the molecular core have been investigated by dielectric relaxation spectroscopy in the range from 1 Hz to 1 MHz. All compound exhibit chiral SmC* phase. The values of Ps in the low temperature derroelectric phase are lower than in the oedinary SmC* phase for the methoxy substituted compounds but shows no anomaly for the non-substituted material.
