Example: NBO analysis: EFG

Download AlCl3_efgnbo.run

Example shows an NBO analysis of an EFG calculation for AlCl3 .

In the ADF input one then needs to include the QTENS (EFG calculation) and include the subkey EFG of the key AORESPONSE. The BeckeGrid quality is good, which may be needed to accurately calculate core properties. Other keywords are necessary because of the NBO analysis afterwards. Note that ADF, ADFNBO, and GENNBO have to run several times.
