 **** 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.

 (3)  G-ENP(sol) elect.-nuc.-pol. free energy of system            -50.672 kcal
 (4)  G-CDS(sol) cavity-dispersion-solvent structure free energy     0.296 kcal
 (5)  G-P-CDS(sol) = G-P(sol) + G-CDS(sol) = (2) + (4)             -30.518 kcal
