Subject:	GAUSSIAN QUESTION (PLEASE READ!!!)

Here is a query for GAUSSIAN92 (or 90,88) users involving checkpoint files
and the --Link1-- option.

I am running a 6-31g* calculation, and the checkpoint file has the name
F4benzylF00.  I then move to a second link, and want to read the force
constants and geometry using:

	opt=readfc  geom=checkpoint

Ok, I can do this, no problem.  What I would like to know: Is there any way
of saving individual checkpoint files as the linked process progresses?  I
am interested in obtaining individual chk files for each basis set I use,
while at the same time reading useful info. out of previous chk files.

I have included a sample run below:

Any help would be appreciated!!


%mem=4000000
%chk=F4benzylF00
# test  rhf/6-31g*  opt  direct
  optcyc=80  iop(2/16=1)

4-fluorobenzylfluoride        Torsion = 00

0 1

..various input..

--Link1--
%chk=F4benzylF00
# test  rhf/6-31g**  opt=readfc  geom=checkpoint  direct
  optcyc=80  iop(2/16=1)

4-fluorobenzylfluoride        Torsion = 00

0 1

--Link1--
%chk=F4benzylF00
# test  rhf/6-311g*  opt=readfc  geom=checkpoint  direct
  optcyc=80  iop(2/16=1)

4-fluorobenzylfluoride        Torsion = 00

0 1

In summary, I would like to have chk files for each of the above three
basis sets.  Any suggestions?


			Thanks a lot,
