ALERT TO GAUSSIAN-03 USERS!
An error in the Gaussian-03 program (DFT XC coding) has been found
to seriously affect $DEL energetic analysis using density
functionals. Gaussian-03 users should therefore include
IOp(5/48=10000)
on the route card whenever the POP=NBODEL option is used.
The problem applies to both G03/NBO3 or upgraded G03/NBO5G versions
of G03, but not to G98 and earlier Gaussian versions.
Thanks to Peter Limacher (ETH-Zurich) for first identifying this problem,
and to Mike Frisch (Gaussian, Inc.) for the IOp solution. The problem
will be repaired in the next minor revision of G03.
