We first focus on the θ = 0 • case. At E = 0eV, the contributions from the lowest unoccupied MO +1 (LUMO+1) and highest occupied MO-1 (HOMO-1) contribute the most to the electronic transmission. These contributions are seen as four dark-red squares in the QI map: two non-interfering terms and two constructively interfering terms. Other destructively interfering terms are much smaller, primarily between the HOMO and LUMO and these two dominant orbitals. At E = -2.23eV, the non-interfering contributions from the HOMO and the HOMO-1 increase while the contributions from the LUMOs decrease nearly to zero. On the contrary, at E = 2.23eV, the tendency is opposite, where the non-interfering contributions from the LUMOs are dominant. The destructive interference between HOMO and HOMO-1 for -2.23eV and that between LUMO and LUMO+1 for 2.23eV are very strong (see the blue blocks), reminiscent of the two orbital interference picture observed for meta-substituted benzene.
