Example: H2 on [PtCl4]2-: charged molecules and PEDA¶

#! /bin/sh

# This example shows that the pEDA formalism can be applied to
# molecules. Here, there is no periodic boundary condition
# necessary. Hence, charged fragments or final molecules can be
# investigated!

#
#
# Fragment 1 is the [PtCl4]2- fragment
