Web27 nov. 2024 · The HOMO-LUMO gap is only weakly correlated with the reactivity of the molecule. Many sources, however, only point out the correlation between the HOMO-LUMO gap and reactivity, but fail to point out that the correlation only holds in the statistical sense, and is by no means universal. Web15 apr. 2024 · I did some energy calculations for geometry optimised compounds and the values given for the HOMO and LUMO energies are negative (e.g. -0.23066 and -0.11119 Hartrees).

This is, in my opinion, the biggest flaw of explaining chemistry transformation at the quantum level. WebThe VIS means that the spectrum was measured over the wavelengths of visible light (roughly 400 – 700 nm). λ is the symbol for the wavelength of the light. And max refers to the wavelength that had the greatest (maximum) absorption of the light. The basic form of phenolphthalein has λ_max = 553 nm (green).
WebThe value of HOMO is always higher than LUMO but is a negative value. In your example, HOMO= -0.29755 an LUMO= -0.094. The Band Gap is -0.094- (-0.29755)= about 0.2 eV. in order to get the ...
