Re: GU: ECPs and Gamess



I am appeding an input file for gamess withnthe proper format to include
ECP's. It does work on Gamess and Gaussian although I am not using
Stuttgart ECPs.

Initially -I think- the program considers all electrons but later the
core electrons are 'eliminated' or replaced by the ECP.

I hope it helps. If you are using similar format it should work okay.
