# Calculation of the excitation energies of Adenine using the simplified time-
# dependent DFT (sTDDFT) method by Grimme. This method is meant for hybrid
# functionals or range-separated functionals during the SCF. In this example the
# hybrid PBE0 is used during the SCF. In the the calculation of the excitation
# energies the sTDDFT method is used in which the required integrals are
# approximated. For hybrid functionals ADF will automatically set the parameters
# that are needed in this method. For range-separated functional one needs to
# set the parameters manually. Symmetry NOSYM is required A TZP or TZ2P basis
# set is recommended for this method.
