frontier molecular orbitalsphotochemistryThe nature of frontier molecular orbitals in complexes of phthalocyanines with p-, d-, and d-elements (magnesium, zinc, aluminum, gallium, and silicon) has been established by means of quantum chemical calculations. The results of the calculations prove that ...
homo lumo轨道理论 HOMO (Highest Occupied Molecular Orbital) and LUMO (Lowest Unoccupied Molecular Orbital) are concepts in quantum chemistry that describe the energy levels of the orbitals in a molecule. The HOMO energy level corresponds to the highest energy level that is occupied by an electron,...
In chemistry, HOMO and LUMO are types of molecular orbitals. The acronyms stand for highest occupied molecular orbital and lowest unoccupied molecular orbital, respectively.

(46). Thus, with an increasing HOMO-LUMO gap, the GVB orbitals gradually become more and more delocalized across the radical centers (Fig. 12), which makes chemical interpretation of the wavefunction in terms of “biradical” and “ionic” contributions impractical in the GVB basis. In fact,...
4. Molecular Orbitals In The [2+2] Cycloaddition Between Ethene And Ethene Show Why The Reaction Is Unfavorable Under “Thermal” Conditions Let’s look at the π molecular orbitals of ethene. The HOMO has zero nodes, and the LUMO has a single node.[We learned how to build up molecular ...
The highest occupied molecular orbitals (HOMOs)of these complexes are composedof a set of distorted degenerated Cr 3d orbitals, whereas the lowest unoccupied molecularorbitals (LUMOs) are predominantly the N-vinylcarbazole ligand π* orbitals. The HOMO?LUMO energy gaps decrease in the order NVC > ...
