Hence, the HOMO - LUMO energy gap of Benzene is 2β. What is HOMO and LUMO ins spectroscopy HOMO is the highest occupied molecular orbital whereas LUMO is the lowest Unoccupied molecular orbital. This lecture then focuses on understanding reactivity in terms of the overlap of singly-occupied molecular orbitals (SOMOs) and, more commonly, of an unusually high-energy highest occupied molecular orbital (HOMO) with an unusually low-energy lowest unoccupied molecular orbital (LUMO). The lowest band gap is predicted to be associated with PORPC-3, while the highest band gap is assigned to PORPC-2 in both the gas phase and in water. Chemical reactivity traits including HOMO-LUMO energy gaps, softness, total energy, chemical hardness, electronic chemical potential, and electrophilicity of. By virtue of the accessible low - lying a orbitals of CO, the fluorenonecontaining organometallic complexes are likely to exhibit smaller HOMO - LUMO. The HOMO is the highest energy MO that has any. HOMOLUMO band gap analyses reveal significantly lower band gaps in the aqueous medium than in the gas phase (see Table S1).

Cyclic conjugated systems take the form:Į = α + 2 β cos \(\frac = α - 2β \) when k = ± 3 These are: the highest occupied molecule orbital or HOMO and the lowest un-occupied molecular orbital or LUMO.
