Re^3: Printing MP2 natural orbitals in the output file (to be used for visualization)

Alex Granovsky

Dear Evgeniy,

this is basically what I had suggested in my post.
In brief, you need to add the following instructions to your input:

 $contrl exetyp=check $end
 $guess guess=moread norb=the_overall_number_of_AOs prtmo=.t. asis=.t.   $end

and copy the appropriate $vec group from the punch file to your input.

The problem is that the version of ChemCraft I use is not capable
to properly detect and read in initial guess orbitals.
This is why I need to cheat a bit and insert some lines from the
standard header of a plain RHF check run to name these orbitals
"Eigenvectors" and make the resulting output looks like RHF calculations.

Maybe this problem is already solved in newer ChemCraft versions,
I did not check this.

All the best,
