This keyword specifies the surface tension coefficient for apolar solvation models.

gamma { value }

where value is a floating point number designating the surface tension in units of kcal mol-1 Å-2. This term can be set to zero to eliminate the SASA contributions to the apolar solvation calculations.


Either this documentation is incorrect or the implementation needs to be changed to use kJ mol-1 Å-2 instead of kcal.
