**** 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 -7.860 kcal
(2) G-P(sol) polarization free energy of solvation -30.192 kcal
(3) G-ENP(sol) elect.-nuc.-pol. free energy of system -38.052 kcal
(4) G-CDS(sol) cavity-dispersion-solvent structure free energy -10.399 kcal
(5) G-P-CDS(sol) = G-P(sol) + G-CDS(sol) = (2) + (4) -40.591 kcal
(6) G-S(sol) free energy of system = (1) + (5) -48.451 kcal
