SAXS (a) and WAXS (b) patterns at 25°C for different DPPC-enflurane mixtures. The Rtot are indicated at the level of each trace: the superscript prime identifies traces measured on D43 line ([lip] = 61 mM). The others are those measured on D22 line ([lip] = 100 mM). Traces 0′ and 4′ are scale-expanded to make visible the higher order of Bragg peaks. (c and d) Long and short spacings as a function of Rtot. Unfilled and solid symbols correspond to measurements on D43 and D22 lines, respectively. (Circles, diamonds, and squares stand for Lβ′1NN, Lβ′2NNN, and Lβi phases, respectively.)
