This keyword specifies the radius of the solvent molecules; this parameter is used to define various solvent-related surfaces and volumes (see srfm). This value is usually set to 1.4 Å for a water-like molecular surface and set to 0 Å for a van der Waals surface. Its syntax is srad {radius} where radius is the floating point value of the solvent radius (in Å).This keyword is ignored for srfm spl2. |
