Can a SMR solvent model be used in energy decomposition by SAPT0?

# Is there a solvent model in SAPT0 energy decomposition?

What does SMR stand for?

To my knowledge consistent solvation treatments for SAPT theory have not been developed yet.

The only chance you have is to calculate SAPT0 interaction energies and do a supermolecular calculation for the dG(solv) terms from SMD (e.g. using Gaussian, PSI4 has no SMD). SMD is calibrated to specific hamiltonians anyway.

A PCM-SAPT theory has not been developed to my knowledge.

Perhaps you could try to enable PCM for the Hartree-Fock calculations and then use the resulting solvent-polarized orbitals from those calculations for SAPT.
