The print out after the SCF cycle in an excited state calculation (ADC/CCSD etc), gives set of EFP energies. One of the terms is particularly confusing:
EFP CORRECTION TO SCF ENERGY 0.104878
Which is calculated here as the sum of all efp energy terms except the “POLARIZATION ENERGY” in the printout. This is confusing, since the efp correction is something that can not be explicitly calculated since it is calculated during the QM-EFP scf procedure.
Maybe the definition “EFP CORRECTION TO SCF ENERGY” is not the right explanation to the quantity that is printed.
