Resumo	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.	Ligand Field Theory (LFT) is an advanced model of metal-ligand bonding that combines crystal field theory with molecular orbital theory. Developed systematically by Brian Norman Figgis and others from the 1960s onward, LFT provides quantitative predictions of electronic structure, magnetism, spectra, and reactivity of coordination complexes, bridging the gap between qualitative crystal field arguments and rigorous quantum mechanics.
