Abstract
The binary systems octyl ammonium chloride-water and potassium oleate-water were oriented in the lamellar phase between glass slides. Proton magnetic resonance at 100 MHz showed reasonably well resolved spectra for magnetic field orientations at the magic angle of 54°44′ with respect to the optical axis. At angles slightly deviating from the magic angle, dipolar broadening and an indication of a splitting of the methylene and methyl protons are observed. At 0 or 90° orientation, a well-defined doublet structure is observed by wide-line techniques. It is concluded that in both systems a section of the hydrocarbon chain with a length of 5–6 carbon atoms near the polar head group has a uniform degree of order, while the molecule as a whole shows a rapid rate of reorientation around the optical axis.
