When using Molden with GAUSSIAN 94/98/03 the
following keywords are required on the GAUSSIAN 94/98/03
inputfile:
#P GFINPUT IOP(6/7=3)
#P switches on
printing of SCF convergence, GFINPUT switches on printing
of Basis Set info, and IOP(6/7=3) switches on printing of
all MO's. GAUSSIAN 94/98 per default uses the redundant coordinates
optimization procedure resulting in only cartesian coordinates being available
on the output file. Molden will covert these into a z-matrix which in general
will have lost the dummys and therefore symmetry at the z-matrix level. Use the
gaussian keyword opt=z-matrix to get z-matrices on the
output.
When using Molden with GAUSSIAN 92 and older versions,
use:
#P GFINPUT IOP(6/7=1)
It doesn't make any reference
to G09, but I presume nothing too significant has changed. Maybe there are some
mysterious settings that you've inadvertently changed in Molden, but I have
no idea what they could be. In the case that something along those lines has
happened, you could try deleting the .moldenrc file in your home directory to
reset any persistent settings to their defaults.
