Partial charges outside of the atoms center

Unfortunately, this is not working.

1) Problem is that the program automatically moves the coordinates.
I solved it with words “nocenter noautosym”.

2) For the first time “task esp” gives the correct dipole moment, but in the second case (with the new geometry) both dipole and partial charges are greatly reduced.
In fact, the dipole moment should remain near the same by increasing the partial charges.
