On the HOMO-LUMO Separation in Fullerenes [PDF]

open access: yesCroatica Chemica Acta, 1993
The isumers uf a given fullerene C„ cuuld be divided into subsets, each characterized by two numbers, p and q. The former denotes the number of bonds shared by two fused pentagons and the latter denotes the number of vertices being common to the triplets of pentagons.

Single excitation energies obtained from the ensemble HOMO-LUMO gap: exact results and approximations [PDF]

open access: yes, 2022
In calculations based on density functional theory, the "HOMO-LUMO gap" (difference between the highest occupied and lowest unoccupied molecular orbital energies) is often used as a low-cost, ad hoc approximation for the lowest excitation energy. Here we

Excited-state energy component analysis for molecules - Why the lowest excited state is not always the HOMO-LUMO transition [PDF]

open access: yes, 2023
The ability to tune excited-state energies is crucial to many areas of molecular design. In many cases this is done based on the energies of the highest occupied (HOMO) and lowest unoccupied (LUMO) molecular orbitals.
