“homo” stands for highest occupied molecular orbital while “lumo” stands for least unoccupied molecular orbital. Corresponds to electron extraction from the homo level and can be correlated to the ionization potential.

The homo is the highest energy molecular.
Lumo and homo. The homo (highest occupied molecular orbital) acts as an electron donor and the lumo (lowest occupied molecular orbital) acts as an electron acceptor. On the one hand, it feels very weird to have both the lumo and the homo be the same orbital, but it also feels like you should be removing electrons from the homo, and. Homo is the highest occupied molecular orbital whereas lumo is the lowest unoccupied molecular orbital.
But i see in dmol 3 program these orbitals in gamma point are predictable. Lumo can't be the same energy level as homo because there is always an energy gap that an electron can cross when it has an energy transition. As shown in figure 4, as the energy difference between lumo and homo gradually increases, higher reaction temperature and/or stronger acid are required for the cyclization to occur [2].
Don't be confused though, because the. If the energy gap is small then the. Homo stands for highest occupied molecular orbital.
So, the best way to remember the terms would be as follows: 1) identify the possible homo’s and lumo’s 2) select the likely nucleophile and electrophile from these two. Sigma 2pz is thus the lumo.
Homo和lumo分别指最高占据分子轨道（highest occupied molecular orbital）和最低未占分子轨道（lowest unoccupied molecular orbital）。 根据前线轨道理论，两者统称前线轨道，处. Homo and lumo conjugated system 0 the particle on a ring is a useful model for the motion of electrons around the porphine ring, the conjugated macrocycle that forms the. As far as i know we can not define frontier molecular orbitals (homo and lumo) for periodic systems.
Cyclic voltammetry the oxidation for specimen i.e. (a) interaction of a singly occupied p orbital (homo) with the a (lumo) of planar mr3 that results in stabilization of the homo on. A high energy gap in p2 and p3 suggests that these polymers are less reactive and more stable than.
What is homo and lumo ins spectroscopy? Oct 25, 2015 homo stands for highest occupied molecular orbital , and lumo stands for lowest unoccupied molecular orbital . This band is shifted from the value of 540 nm, typical.
Lumo stands for lowest unoccupied molecular orbital.the energy difference between the homo and lumo is termed the homo.
