Zusammenfassung:Equations for the reduced structure function and atomic pair distribution function (PDF) of a textured polycrystalline sample are formulated in terms of the orientational distribution function (ODF) and the structure function from a single crystallite. This may be used to determine the sample ODF from experimental data when the structure of the reference crystallite is known.
