Özet
The decylammonium chloride (DACl), KCl and D2O system forms two phases(N-c+N-d) in the nematic range. The N-d phase was ca. 15% by volume and exhibited extinct appearance. From conoscopic measurements it was inferred that the optical axis of the N-d phase was tilted. The lamellar phase of the DACl-KCl-D2O system as well as the lamellar phase obtained by adding phosphoric acid decylester/phosphoric acid (PDE/H3PO4) showed the following phase sequence: GRAPHICS isotropic The line shapes of P-31 NMR of PDE/H3PO4 were found to be sensitive to micelle size and dynamics occuring in the lyotropic system, but they do not differentiate between different micelle shapes.
