Abstract     The dynamic properties of chiral smectic liquid crystals are studied theoretically by including competing interlayer interactions leading to the smectic C* alpha phase below the smectic A phase. In the smectic A phase only one doubly degenerate soft mode exists which becomes critical at the transition temperature for the critical wave vector corresponding to the helicoidal modulation extending over only a few smectic layers. In the tilted smectic C* alpha it splits into two modes, i.e. a phase and an amplitude mode.
