Single Crystal X-ray Diffraction (SCXRD) is a powerful analytical technique used to determine the atomic and molecular arrangements within crystalline materials. It is based on the interaction of X-rays with electrons in crystalline materials, which produces a diffraction pattern that can be analyzed to obtain detailed information about the crystal structure. A perfect crystal possesses many periodically arranged blocks, or unit cells, in a three-dimensional lattice. The crystal lattice can be considered as a 3D diffraction grating, and when a beam of parallel monochromatic X-rays of the right wavelength hits the lattice, a diffraction pattern is generated. From the analysis of the diffraction pattern, the dimensions and shape of the unit cell can be determined, as well as the orientation and spacing of the atoms within the crystal.
