CCL:G: What to change in gaussian03 to calculate thermochemistry?

 Hi Taye (and also Steve),
 Since the AM1 and UAM1 keywords activate the old code in l402 for
 wavefunction and gradient calculation SCF keywords won't help. One
 useful trick is using "UHF Int=AM1" insted of UAM1 which will use the
 regular SCF code (l502) for the semiempirical calculation. This should
 help on its own and also, SCF=QC should work is necessary.
 Best wishes,
 Odon
