`EPS=n.nn`

Sets the dielectric constant for the solvent to n.nn. Presence of this keyword will cause the COSMO (Conductor-like Screening Model) method [30] to be used to approximate the effect of a solvent model surrounding the molecule. Solvents with low dielectric constant are not likely to work well in this model. A test is provided to allow COSMO to be validated.

To alter the Van der Waals radius, use VDW.
