Given the standard output

QM/MM Energy

quantum energy 537.200184022 (.141042E+07 kjoule/mol)
quantum energy adjusted 537.200184022 (.141042E+07 kjoule/mol)
quantum energy internal 537.135248946 (.141025E+07 kjoule/mol)
Bqnuclear energy 3.733295197 (0.980177E+04 kjoule/mol)
Bqelectron energy 3.798230274 (.997225E+04 kjoule/mol)
classical energy 16.117550021 (.423166E+05 kjoule/mol)
total qmmm energy 553.317734044 (.145274E+07 kjoule/mol)

the electrostatic interaction energy can be calculated as sum of "Bqnuclear energy" and "Bqelectron energy", or as a difference between
"quantum energy" and "quantum energy internal". Vdw interaction energy and others ( e.g. bonded, etc) are unfortunately buried in the "classical energy" term. Please note that a single interaction energy number would likely be meaningless.
