Anisotropic self-diffusion coefficient tensor was determined in the smectic Ad (S,) phase of a polar mesogen CBOOA. The pulsed-field-gradient stimulated-spin-echo NMR technique was applied in combination with angular displacement of a quadrupole coil, to obtain the diffusion coef&ient components bot
Transport in cellulose gels has been studied with ethylene glycol and crown ether (15-5) as "probes" using an NMR spin-echo technique. The cellulose content was varied in range 20-5570 (w/w). The retardation of diffusion was found to be adequately described by simple first-order expressions in conce
