Hallo,
i cant understand how to find out which orbitals are proper or not!
How can i see what to reorder?

For example
I made calculations of Transition state of reaction O3+C2H4 in basis 6-311pg**:

1)by the means of ss cas(8,8) - name of file           d_c2h4o3_cas.inp
2)i calculated the caspt2 energy - name of file        d_c2h4o3_cas_pt2.inp

Don`t pay attention than files were made for GAMES US, i made this calculation
in pcgamess too, but i could not find them.

Thank you very much/
