# pdie

Specify the dielectric constant of the solute molecule. The syntax is:

    pdie {diel}

where `diel` is the floating point value of the unitless biomolecular dielectric constant. This is usually a value between 2 to 20, where lower values consider only electronic polarization and higher values consider additional polarization due to intramolecular motion. The dielectric value must be \(\ge 1\).
