Hello Amber!
I am trying to do RESP charge fitting for an alkyl-modified phosphate. My
input file is below. The fitting runs fine, but does not incorporate my
desired charge constraint (the last eight atoms' charges must be equal to
-1.0). I looked at example files and see no meaningful difference, so I am
stuck. Please help!
Best,
Dan
