COSMO

AMPAC provides several keywords for incorporating solvation into a calculation. The simplest and most general is COSMO. (See Chapter 14, COSMO Solvation Model for details and related keywords.) For demonstration, the properties of alanine are calculated in water. (Water is assumed to be the solvent unless otherwise specified.)

The Van der Waals radii for each element used in the COSMO calculation. These default values may be overridden using the VDW keyword.

2

The solvation energy is directly included in the heat of formation and total energy.

3

Total surface area in the COSMO calculation.

AMSOL

The AMSOL module methods provide a powerful alternative to COSMO. AMSOL comes in several variants as described in Chapter 15, AMSOL Model Module. As an example, trichloroethane in cyclohexane using SM5.2R is shown.

SM5.2R has been specified as the solvation method. Keyword 1SCF is required because SM5.2R specifies a rigid solvation model. TRUES specifies that the true solvation free energy is to be computed and requires HGAS to be specified as well. HGAS gives gas phase heat of formation, which is determined by a gas-phase MNDO calculation. (The input geometry, which is used for both the gas-phase and the liquid-phase MNDO calculations, was calculated at the HF/MIDI! level.)

 1SCF run. The solvation energy has been calculated at the input geometry.    3
 If that was an optimized gas-phase geometry, the result may be denoted SM5.2R.
 If the input geometry was not an optimized gas-phase geometry,
 the result should be labeled as a non-optimized SM5.2 calculation.

  Comment

 1SCF run. The solvation energy has been calculated at the input geometry.    4
 If that was an optimized gas-phase geometry, the result may be denoted SM5.2R.
 If the input geometry was not an optimized gas-phase geometry,
 the result should be labeled as a non-optimized SM5.2 calculation.

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


 (0) E-EN(g) gas-phase electronic-nuclear energy                     -4.747 kcal

    This is a breakdown of the true solvation energy:

 (1) E-EN(s) electronic-nuclear energy of solute                     -4.678 kcal
 (2) G-P(s) polarization free energy of solvation                    -0.469 kcal
 (3) G-ENP(s) elect.-nuc.-pol. free energy of system = (1) + (2)     -5.147 kcal
 (4) G-CDS(s) cavity-dispersion-solvent structure free energy        -2.864 kcal
 (5) G-P-CDS(s) = G-P(s) + G-CDS(s) = (2) + (4)                      -3.333 kcal
 (6) G-S(s) free energy of system = (1) + (5)                        -8.011 kcal
 (7) DeltaE-EN(s) elect.-nuc. reorganization energy of solute         0.068 kcal
     (7) = (1) - (0)
 (8) DeltaG-ENP(s) elect.-nuc.-pol. free energy of solvation         -0.401 kcal
     (8) = (3) - (0)
 (9) DeltaG-S(s) free energy of solvation                            -3.265 kcal
     (9) = (6) - (0) = (5) + (7)
