- 1. Crystallography is the study of the arrangement of atoms in crystalline solids. It reveals the internal structure of crystals at the atomic and molecular levels, providing valuable insights into their physical and chemical properties. By analyzing the geometric arrangement of atoms in a crystal lattice, crystallographers can determine the symmetry, bonding patterns, and overall architecture of the material. This information is essential for understanding the behavior of crystals in fields such as materials science, chemistry, physics, and biology. Crystallography plays a crucial role in designing new materials with specific properties, investigating the structures of biomolecules, solving complex chemical structures, and advancing various technological applications.
