# gamma

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 kJ mol-1 Å-2. This term can be set to zero to eliminate the SASA contributions to the apolar solvation calculations.
