This is, in my opinion, the biggest flaw of explaining chemistry transformation at the quantum level. In chemistry, HOMO and LUMO are types of molecular orbitals. The acronyms stand for highest occupied molecular orbital and lowest unoccupied molecular orbital, respectively. HOMO and LUMO are sometimes collectively called the frontier orbitals, such as in the frontier molecular orbital theory.

Web24 nov. 2024 · HOMO characterizes the ligand’s ability to donate an electron, whereas LUMO refers to the ability of the ligand to accept an electron. Low values of LUMO indicate the higher propensity of the molecule to accept electrons, whereas higher values of HOMO dictate the increased propensity to donate electrons to unoccupied molecular orbitals. WebThe value of HOMO is always higher than LUMO but is a negative value. In your example, HOMO= -0.29755 an LUMO= -0.094. The Band Gap is -0.094- (-0.29755)= about 0.2 eV. in order to get the ...
