Charge Distribution Preferences
Defaults for the items in the Charge
Distribution dialog can be set with the Charge
Distribution Preferences panel (see the figure below).

Charge Distribution Preferences
This preference panel specifies how atomic charge results are
visualized, using these options:
- Show Numbers: Place
atomic charge values next to each atom.
- Color Atoms by Charge:
Recolor each atom by atomic charge according to the specifications of
the Color Range fields and the Symmetric Color Range checkbox.
- Symmetric Color Range:
Forces the positive and negative limits of the charge range to have the
same absolute magnitude (regardless of the actual range of the atomic
charge values).
- Fixed Color Range: Force
the charge display to use the default fixed range. This range is set to
-1.0 to 1.0 by default, and it can be modified in the Charge Distribution Preferences.
- The Dipole Moment area
of the dialog controls whether a vector representing the dipole moment
is included in the display. When the vector is displayed, you can
specify the scaling factor for the vector’s length (the default is
about 1.0) using the slider control.
