Dear all,
it seems that turbomole calculates the DFT-D4 correction always assuming a neutral molecule by default.
As the D4 correction depends on the charge of the molecule, the correction is wrong for charged systems.
At the moment one can fix this by stating the charge explicitly, e.g. for a negatively charged molecule:
$disp4 chrg -1
It would be nice however, if the correct charge would be adopted automatically by the dftd4 code.
Best wishes,
Christian
