This paper reports observation, in a mixture of potassium palmitate-d3, potassium laurate, and water, of a lamellar phase above 41°C, a phase of elongated cylindrical aggregates below 36°C, and, in the intermediate temperature region, a phase in which the H2-NMR spectral patterns can be calculated from a model of elongated ribbon-shaped aggregates. The size of the ribbons can be determined from the spectra and is found to vary with temperature. The results are consistent with H2-NMR spectra of H2O2 in the same and other ternary mixtures. © 1982 The American Physical Society.

Abstract
This paper reports observation, in a mixture of potassium palmitate-d3, potassium laurate, and water, of a lamellar phase above 41°C, a phase of elongated cylindrical aggregates below 36°C, and, in the intermediate temperature region, a phase in which the H2-NMR spectral patterns can be calculated from a model of elongated ribbon-shaped aggregates. The size of the ribbons can be determined from the spectra and is found to vary with temperature. The results are consistent with H2-NMR spectra of H2O2 in the same and other ternary mixtures. © 1982 The American Physical Society.File in questo prodotto:
