Function
CHEMPROPSTD_CONNOLLY_MOLECULAR_AREA(cell ref)
Example
In cell: =CHEMPROPSTD_CONNOLLY_MOLECULAR_AREA(A2)
Result: 212.294
Note: The default probe radius used in the calculations is 1.4 angstroms.
Note: The surface area calculation is performed with Michael Connolly's program for computing molecular surface
areas and volume (M.L. Connolly. The Molecular Surface Package. J. Mol. Graphics 1993, 11).
Connolly solvent-excluded volume
The volume contained within the contact molecular surface.

Function
CHEMPROPSTD_CONNOLLY_SOLVENT_EXCLUDED_VOLUME(cell ref)
Example
In cell: =CHEMPROPSTD_CONNOLLY_SOLVENT_EXCLUDED_VOLUME(A2)
Result: 170.277
Note: The volume calculation is performed with Michael Connolly's program for computing molecular surface
areas and volume (M.L. Connolly. The Molecular Surface Package. J. Mol. Graphics 1993, 11).
Ovality
The ratio of the molecular surface area to the minimum surface area. The minimum surface area is the surface area of
a sphere having a value equal to the solvent-excluded volume of the molecule. Computed from the Connolly Molecular
Surface Area and Solvent-Excluded Volume properties.
