Measurements are made of the temperature dependences of the spin relaxation times T1, T1 rho, and T2 of the 23.Na nucleus in the uniaxial ferroelectric AgNa(NO2)2. Although none of these quantities shows an anomalous behaviour near Tc their temperature dependences can be ascribed to the dynamics of the electric dipoles which cause the ferroelectricity.
