A number of consequences of the presence of the exchange-correlation hole potential in the Kohn-Sham potential are elucidated and the spurious nature of HF LUMOs if the orbital energy is positive is stressed.

It is found that TD-DFT with all functionals accurately predicts the HOMO-LUMO gaps and a linear correlation between the calculated HomO eigenvalue and the experimental -IP and calculated Homeric gap and experimental lowest excitation energy enables us to derive a simple correction formula.
