Resumo: A lyotropic nonionic lamellar system composed of pentaethyleneglycol mono n-dodecyl ether and D2O was studied using natural abundance C-13 NMR under magic-angle spinning. Applying a two-dimensional recoupling method proposed by Dvinskikh (R-PDLF), H-1-C-13 dipolar couplings were estimated over a range of temperatures (300-335 K), thus enabling analysis of structural changes in the liquid crystalline system. The results obtained are used to correlate the conformation and mobility of local sites in the surfactant molecule with overall changes in the lamellar structure.
