Input
By default, the charges are read from the input stream, one per line, in this format:
x y z charge
where x,y,z are the coordinates in the standard orientation (in the units specified by the Units keyword and defaulting to Angstroms), and charge is the charge.
Availability
Single point energies, optimizations and frequencies. Not valid with semi-empirical methods or PBC.

Examples
To perform geometry optimizations in the presence of background charges, you must use Opt=Z-Matrix NoSymm keywords and define the input geometry either in traditional Z-matrix coordinates or symbolic Cartesian coordinates. Here is an example:
# B3LYP/6=31G(d) Opt=Z-Matrix Charge NoSymm Water with point charges 0,1 O -0.75 -0.94 0.0 H 0.21 -0.94 0.0 H-1.07 -0.0 0.0 2.0 2.0 2.0 1.2 2.0 -2.0 2.0 1.1
