WebAug 28, 2024 · The first is known as the traditional method, which is very straightforward, and bears resemblance to single crystal data analysis. This method involves a two step process: 1) the intensities and diffraction patterns from the sample is collected, and 2) the data is analyzed to produce a crystalline structure. WebA symmetry plane of a crystal necessarily cuts the spherical projection of the crystal along a great circle. It is therefore represented on the stereogram by a line which will be either the primitive, a diameter of the primitive, or …
