Dear Isveracool,
your job running was aborted during a SCF- procedure and there is severe spin
contamination.
So, I think that the correct route section should be
#p uhf/6-311++g** scf=(vshift=100,xqc,tight,maxcycle=512)
# scrf(pcm,read,solvent=water)
Sincerely,
Ol Ga
ps. if you get an error in SCF-procedure try to use DAMP and NDamp keywords in
an appropriate way or change the basis set.

the head file is :
#p hf/6-311++g** scf=tight scrf(pcm,read,solvent=water)
the error termination is :
Annihilation of the first spin contaminant:
S**2 before annihilation 0.8506, after 0.7572
Convergence failure -- run terminated.
Error termination via Lnk1e in /home/user/ustcguo/g03/l502.exe at Wed Jul 23
22:02:34 2008.
Job cpu time: 0 days 0 hours 31 minutes 45.5 seconds.
File lengths (MBytes): RWF= 82 Int= 0 D2E= 0 Chk= 2 Scr=
1
DeltaG (solv) (kcal/mol) = -64.82
the result comes out, but I wonder whether it is correct. because I 've
calculated a file which gave two different DeltaGs on two mechines.
thanks for the help!
