The question in the title was vague for me all the time. I've failed to find a clear answer in the firefly documentation.
1) Does TOTAL FREE ENERGY IN SOLVENT include entropy contribution of a solute?
2) Why in e.g. MP2 energy calculation FREE ENERGY IN SOLVENT = E(0), not =E(MP2) from RHF-MP2 ENERGY CALCULATION?
Perhaps, It would be a good thing if the contributions to the TOTAL FREE ENERGY IN SOLVENT were explicitly documented in the Firefly manual... If this term really doesn't include the entropy contribution from the solute, then better write down this explicitly.
I will be grateful for your answer.
