Abstract A sequence of hydrogen bond ferroelectric liquid crystals (HBFLC), derived from Camphoric acid and alkyloxy benzoic acids display a variety of mosogenic polymorphism with various smectic ordering like C*, X* and G*. FTIR spectra and dielectric relaxations in smectic C* and smectic X* are studied. A new method to elucidate the helicoidal structure variation with temperature through dielectric investigations is discussed. Thermistor which exhibits both positive and negative temperature coefficients is derived from the present liquid crystals and results are also discussed.
