# The Bader atomic charges are calculated using a grid based method. Another
# possibility for Bader's analysis is to use the adf2aim utility such that a
# third party program Xaim can be used.

# With the QTAIM input block the ADF program will calculate Bader charges (AIM
# charges) using a grid based method.
