Item Fluorocarbon Surfactant/Water Mesomorphic Phases Part: 4.—Study of the Distribution of Alkyl Chain Mobilities in the Lamellar Phase of the Sodium 12,12,13,13,14,14,14-Heptafluoromyristate/D2O System by 19F and JH Spin Echo Nuclear Magnetic Resonance(Journal of the Chemical Society : Faraday Transaction - I. The Chemical Society, London. 1972, 68 (4), 1972) Tiddy, G J T19F and 1H spin lattice and spin-spin relaxation times for a lamellar phase sample of the above system indicate that little or no distribution of correlation times for alkyl chain motions exists. The difference between this result and conclusions from c.s.r. spin probe studies is discussed in terms of the ease of internal chain motions as the distance between CH2 groups and the head group increases and differences in molecular structures
