Abstract
The temperature dependence of the conductivity is shown to be governed by the segmental chain motion. The frequency dependence of the phosphorus spin-lattice relaxation rate is interpreted using a stretched exponential correlation function exp[−(t/τ)β] with β=0.277. The long-range diffusion coefficient of the molecule (measured by the pulsed field gradient NMR technique) is shown to be quite close to the short-range diffusion coefficient of the chain segments determined from NQES.
