Biological membrane assemblies with two membranes per unit cell and with well defined fluid layers are treated. In membrane diffraction the minus fluid model is used. A method for the determination of the zero‐order amplitude using knowledge of the membrane‐pair width is described. Sampling‐theorem expressions for the Fourier transform of the individual membranes are derived. These expressions simplify the structural analysis and the interpretation of modified and disordered membrane systems.
