A global analysis model has been developed for randomly oriented; fully hydrated; inverted hexagonal (HII) phases formed by many amphiphiles in aqueous solution; including membrane lipids. The model is based on a structure factor for hexagonally packed rods and a compositional model for the scattering length density; enabling also the analysis of positionally weakly correlated HII phases. Bayesian probability theory was used for optimization of the adjustable parameters; which allows parameter correlations to be retrieved in much more detail than standard analysis techniques and thereby enables a realistic error analysis. The model was applied to different phosphatidylethanolamines; including previously unreported HII data for diC14:0 and diC16:1 phosphatidylethanolamine. The extracted structural features include intrinsic lipid curvature; hydrocarbon chain length and area per lipid at the position of the neutral plane. © Moritz P. K. Frewein et al. 2019;
