Re^6: FOOF torsional potential

Alex Granovsky

Dear Alexey,

sorry for delay on my side.

Basically, this is the problem of selecting proper active space
for the underlying CASSCF. The rest is quite often more or less technical.
If you have an input for MCSCF for this system
I'll show you how to convert it to XMCQDPT2 input.

All the best,
