Description of the EFP usage in Q-Chem can be found in “Effective Fragment Potential method” section of the Q-Chem manual EFP in Q-Chem.
The following functionality is available:
stand-alone EFP calculations
QM/EFP models (single-point energy only, polarizable embedding)
basic HF and DFT
coupled cluster and equation-of-motion methods via interface with CCMAN and CCMAN2 (CCSD, EOM-CCSD and various EOM variants (EE, IP, EA, SF etc.))
valence and core exciations
two-photon absorpion calculations
ADC family of methods
CIS and TF-DFT calculations
perturbative corrections for electronic excited states due to interaction with polarizable environment
pairwise interaction energy decomposition analysis for ground and excited states
