The energy difference between the HOMO and LUMO is the HOMO–LUMO gap. Its size can be used to predict the strength and stability of transition metal complexes, as well as the colors they produce in solution.As a rule of thumb, the larger a compound's HOMO-LUMO gap, the more stable the compound. See more The HOMO level is to organic semiconductors roughly what the maximum valence band is to inorganic semiconductors and quantum dots. The same analogy can be made between the LUMO level and the … See more In organometallic chemistry, the size of the LUMO lobe can help predict where addition to pi ligandswill occur. See more If existent, the molecular orbitals at one energy level below the HOMO and one energy level above the LUMO are also found to play a role in … See more A SOMO is a singly occupied molecular orbital such as half-filled HOMO of a radical.
