The effect of the hydration level on X-ray-induced changes in low-angle diffraction behavior of the (001) reflection of Lα (338 K) and the (001) reflection of Lβ′ (303 K) phases of DPPC. (a) 46% w/w water; (b) 34% w/w water; (c) 14% w/w water. Lines are drawn to guide the eye. A schematic temperature-composition phase diagram for DPPC/water is shown as an inset in (c). In the inset, X and O identify, respectively, sample compositions where the water-stressed and fully hydrated conditions prevail. Diffraction patterns were collected on the A1 station at CHESS (8 keV, 2 × 1010 photons s−1). Modified from Fig. 4 of Cheng & Caffrey (1996BB2).
