Pulsed-field-gradient spin-echo (PGSE) nuclear magnetic resonance (NMR), combined with a quadrupole-coil rotation, was applied to the study of anisotropic self-diffusion in the smectic A phase of an antiferroelectric chiral liquid crystal MHPOBC. It was shown that diffusion within the smectic layer was significantly faster than that across the layers. The activation energies, $E_{\text{a}}$, are also significantly different: $E_{\text{a}}$ for the in-layer diffusion was 30 kJ mol-1, and that for the interlayer diffusion was 93 kJ mol-1.
