خلاصه	Molecular symmetry analysis is the systematic application of group theory to understand the structure, bonding, spectroscopy, and reactivity of molecules. Developed comprehensively by F. Albert Cotton and others from the 1960s onward, this framework uses the mathematical properties of molecular symmetry to predict allowed electronic transitions, molecular orbital shapes, vibrational modes, and reaction pathways.	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.
