Abstract
This is a report on P-31 nmr spectra of phosphoric acid monodecylester, PDE, and H-2 quadrupolar splitting of D2O in a lyomesophase developed from n-decylammonium chloride, PDE/H3PO4 and D2O. Polarizing microcopic and H-2 nmr studies showed that the mesophase was of lamellar-like structure but alignes as the temperature is increased. As the mesophase contained a minute amount of free H3PO4, the P-31 nmr spectra gave a sharp peak and a hump. The latter was interpreted to arise from a slow tumbling process of PDE between different agglomerates in this system.
