Application: It can be used to determine the exact steric structure of a new compound (crystalline) molecule, giving detailed bond lengths, bond angles, configurations, conformations, and even bonding electron density and arrangement of molecules in the crystal lattice. Meanwhile, it can provide information on the microstructure of crystalline materials at the molecular and atomic levels. And also it is widely and importantly applied in the fields of chemistry, physics, biology, material science, and mineralogy, it is an important tool for understanding the microstructure of matter.
