I am concerned about the units of the ESP in NWChem. Consider the data on HF in the output file:

1 a.u. = 9.07618 esu/cm ( or statvolts ) 
Point X Y Z Total Potential(a.u.) Diamagnetic shielding(a.u.)
   1 F    0.00000   0.00000  -0.08806     -26.551580            27.123542
2 H 0.00000 0.00000 1.66031 -0.905417 6.053075

Now consider the same data from Gamess on the same molecule:

electric potential 1 a.u. = 9.076814E-02 esu/cm

                                 Total Potential (a.u.)             Diamagnetic shielding (a.u.)
F -26.554587 27.126252
H -0.902754 6.047740

Is it possible that NWChem has an error in the conversion factor from a.u. to esu/cm?
