Hello everyone,
I am trying to generate a force field for trimethylamine. I have optimized the
geometry and obtained the charges using Gaussian 03. I then execute the
following command to assign RESP charges using antechamber:
antechamber -i tma-resp.log -fi gout -o tma.prepin -fo prepi -c resp -nc 0
The assigned charges are reasonable except that the total charge of the molecule
is 0.004e. It seems that if antechamber kept 4 decimal places, the assigned
charges would be closer to zero. Any ideas how to fix this?
Thanks,
