Hello all!

Well, this is just an mail message with the conclusions on "how to
take the esp grid points from the gamess program?". Just sending, so
maybe it'll can help someother people in the future. Thank you all for the
help, specially for Dr. M. Froeyen.

Well, here we go: the recipe to make it works was gived by Dr.
Froeyen, and those are the input files that I've used for the CCl4
molecule. In order to obtain the optimized structure of CCl4, it was:

$CONTRL SCFTYP=RHF RUNTYP=OPTIMIZE COORD=CART $END
$CONTRL MOLPLT=.TRUE. UNITS=ANGS EXETYP=RUN ICHARG=0 $END
$SYSTEM MEMORY=900000 $END
$SCF DIRSCF=.TRUE. $END
$STATPT NSTEP=1000 $END
$BASIS GBASIS=N31 NGAUSS=6 NDFUNC=1 $END
$ELPOT IEPOT=0 $END
$GUESS GUESS=HUCKEL $END
$DATA

$END

Then, in the single-step run for energy (in order to get the ESP
Grid Points), we used this input:

$CONTRL SCFTYP=RHF RUNTYP=ENERGY COORD=CART $END
$CONTRL MOLPLT=.TRUE. UNITS=ANGS EXETYP=RUN ICHARG=0 $END
$SYSTEM MEMORY=800000 $END
$SCF DIRSCF=.TRUE. $END

$ELPOT IEPOT=1 WHERE=PDC OUTPUT=PUNCH $END
$PDC PTSEL=CONNOLLY CONSTR=NONE $END
$GUESS GUESS=HUCKEL $END

Maybe it can help someone. Again, really thank you all for the
help.

Sincerally yours,

Jones
