# Calculation of damped complex polarizabilities of Au10
# with POLTDDFT.
# It is very important to use basis sets with specially made
# auxiliary fit sets available in $AMSHOME/atomicdata/ADF/POLTDDFT
#
# Symmetry irreps are chosen which for which the electronic transitions
# are dipole allowed.
# The analysis option is used, which will give an analysis
# of the absorption and CD spectrum in terms of single orbital transitions.
# If the regionsforanalysis option is used, the absorption and CD spectrum 
# will be split in region_i -> region_j terms.
