• We have investigated molecular motion and ordering in the smectic phases of a nonoriented antiferroelectric liquid crystal by means of C-13 NMR and powder X-ray diffraction. The marked line broadenings for core carbons observed by C-13 NMR indicate the existence of the characteristic molecular motion for the molecular core in the antiferroelectric chiral smectic C (SmC^*_A) phase. In the smectic phases appearing during the cooling and heating processes, local and overall molecular motions of each molecule observed by C-13 NMR are discussed in comparison with long-range order inside the layer observed by X-ray diffraction.
