Hello.
I want to know the ESP on the grid point using the Gaussian.

When I calculated the Single point energy using the Gaussian, I can get the ESP on the atomic center and grid point location as below.
But I also want to know the ESP on the ESP fit center(grid point).

I got the information that Antechamber can make the Gaussian input file that can get the ESP on the ESP fit center.

Best regard.



This is Gaussian output file.
