X-Ray Powder Diffraction (XRPD) is a somewhat inefficient measurement technique • Only a small fraction of crystallites in the sample actually contribute to the observed diffraction pattern – Other crystallites are not oriented properly to produce diffraction from any planes of atoms – You can increase the number of crystallites that contribute to the measured pattern by spinning the
The experiment consists of analysing two x-ray films exposed in a powder diffraction camera. In the powder (Debye-Scherrer) method, the x-rays fall on a mass of tiny crystals in all orientations, and the diffracted beams of each order h , k , l form a cone.

Differences were observed when X-ray powder diffraction data obtained for stearic acid and zinc stearate were compared to published data for these two compounds (PDF 38-1923 and 5-0079, respectively). In the case of stearic acid, differences could be explained by the fact that the specimen reported previously in PDF 38-1923 was likely contaminated with palmitic acid. In the case of zinc
