 **** NOTA BENE ****
 This is the net solvation energy for this exact molecular structure 
 (nuclear and electronic)!  The standard-state solvation energy should be 
 obtained as the difference between the heat of formation plus delta-G solvation
 for the relaxed solvated system and that for the relaxed gas-phase system.

    This is a breakdown of the solvation energy calculated
    without geometric relaxation in solution:

 (1)  E-EN(sol) electronic-nuclear energy of solute                 95.433 kcal
 (2)  G-P(sol) polarization free energy of solvation               -31.780 kcal
 (3)  G-ENP(sol) elect.-nuc.-pol. free energy of system             63.653 kcal
 (4)  G-CDS(sol) cavity-dispersion-solvent structure free energy    -9.314 kcal
 (5)  G-P-CDS(sol) = G-P(sol) + G-CDS(sol) = (2) + (4)             -41.093 kcal
 (6)  G-S(sol) free energy of system = (1) + (5)                    54.339 kcal
