Abstract
The frequency dispersion and anisotropy of nuclear spin relaxation caused by order director fluctuations in the smectic A phase are calculated. Dispersion of (T−11)OF at low frequencies, which departs from the nematic‐like behavior, is examined in detail and the influence of the wave vector dependent viscosity coefficients on relaxation is commented. The deviation from the nematic‐like relaxation behavior drastically changes the angular dependence of (T−11ρ)OF.Keywords
