Homo lumo mo theory
WebThe corresponding delocalized "HOMO-LUMO picture" is far less straightforward. As shown in the first section of CMO output above, and illustrated in orbital diagrams below, the HOMO (MO 17) is found to be the "antibonding mixture" of π-type n S', n S" NBOs on each monomer, viz., HOMO = MO 17 = 2-1/2 [n S' - n S"] WebFirst of all, the general perturbation theory of the HOMO-LUMO interac-tion between two molecules was built up by Salem. 23-25 One of Salem’s papers 25 was in line with the important theory of Bader, 26 which specified the mode of decomposition of a molecule or a transition complex by means of the

WebFrontier Orbital Theory. A powerful practical model for describing chemical reactivity is the frontier molecular orbital (FMO) theory, developed by Kenichi Fukui in the 1950's. An important aspect of the FMO theory is the focus on the highest occupied and lowest unoccupied molecular orbitals (HOMO and LUMO).
