Hydration Water Freezing in Single Supported Lipid Bilayers

Table 1

Neutron detectors (D1–D16), corresponding center q_||-value, length scales, and type of scattering and motion detected. The lipid acyl chain correlation peak is centered q_|| ~1.5 Å⁻¹. The hydration water correlation peak was reported at q_|| = 1.85 Å⁻¹ [9, 10, 15].
