WebThe commonly used practical model for describing the mechanisms of chemical reactivity is the frontier molecular orbital (FMO) theory, which was developed by the Nobel laureate Fukui in 1950 [32]. The chemical reaction of a molecule is dominated by two frontier orbitals, namely the HOMO and LUMO. WebThis paper discusses the effect mechanism of auxochrome of electronic spectrum.
