Sammanfattning	X-ray crystallography is a technique that determines the three-dimensional atomic structure of crystals by analyzing the diffraction patterns produced when X-rays pass through them. Developed by William Henry Bragg and William Lawrence Bragg in 1912, X-ray crystallography has become the gold standard for structure determination in chemistry, biochemistry, and materials science, winning multiple Nobel Prizes for its profound impact.	Crystal Field Theory (CFT) is a model that explains the electronic structure, color, magnetism, and reactivity of coordination complexes by considering how the electric field created by surrounding ligands perturbs the d-orbitals of a central metal ion. Developed by Hans Bethe in 1929 and refined throughout the 20th century, CFT is one of the most powerful tools for understanding inorganic chemistry.	Stereochemistry analysis is the systematic study of three-dimensional molecular structures, with emphasis on determining the spatial arrangement of atoms around chiral centers and assigning unambiguous names to stereoisomers. Formalized by Cahn, Ingold, and Prelog in 1966, the CIP (Cahn-Ingold-Prelog) rules provide an objective method for assigning R/S (or E/Z) nomenclature, enabling unambiguous communication of molecular structure.
