Coordination chemistry provides the necessary tools for tailoring such properties in, for instance, coordination solids and metal-organic frameworks (mofs) a judicious choice of metal ion and organic ligand modules can critically affect the electronic energy level spectrum of the material and thus dictate the overall physical properties. 13-1 electronic spectra of complexes • interpret electronic spectra of coordination compounds correlate with bonding orbital filling and electronic transitions electron-electron repulsion application of mo theory • spectroscopic terms • complex transitions ligand field charge transfer selection rules. Spectroscopy is used in physical and analytical chemistry because atoms and molecules have unique spectra as a result, these spectra can be used to detect, identify and quantify information about the atoms and molecules.
