# Modify ORCA orbitals for CASSCF

I have run a HF calculation on naphthalene and I have checked the MOs that have been obtained. Now, I have to select my active and inactive orbitals for CASCF(10,10). As there are 34 occupied orbitals, ORCA by default would read 31, 32, 33, 34, 35, 36, 37, 38, 39 but I have inspected how they look and I should use 27, 32, 32, 33, 34, 35, 36, 37, 41 and 48.

So the changes to be done are:

30 to 27 38 to 41 39 to 48

How do you tell ORCA to read the MOs from output file and to change the default selection of the orbitals to the ones I chose? Thank you

%scf rotate {30,27,90} (38,41,90} {39,48,90} end end
