Applications of the Excitation feature in ADF

It may be useful to consult the following (early) applications of the Excitation feature in ADF:

1. For excitation energies based on exact XC potentials: [82]
2. Calculations on Free Base Porphin: [83]; calculations on metal-porphyrins:
   a series of papers by Rosa, Ricciardi, Baerends, e.g. [84,85].
3. Calculations on MnO4-, Ni(CO)4 and Mn2(CO)10: [86]
4. Calculations on M(CO)5 (M=Cr, Mo, W), using the scalar ZORA relativistic approach: [87]
5. Excitation energies of open-shell molecules: [154,157]
6. Calculations on [PtCl₄]^2-, [PtCl₄]^2-, and [PtCl₄]^2-, using the ZORA relativistic approach including spin-orbit coupling: [183]
