I'm trying to convert an ORCA output file into MOLDEN file (via molden itself).

I hit the "Write" button and it converts the file, yes, but the displacement vector s are zeros. I need that information in that specific file formatting.

What can I do?

    $\begingroup$ I think you can use orca_2mkl tool (provided with Orca) to get molden files from Orca. What kind of displacement vector do you need? Is this for vibrational modes? $\endgroup$

    $\begingroup$ @SRMaiti yes I need vibrational modes. I tried that plugin, but it does not convert also the vibrations. $\endgroup$

  • $\begingroup$ It would help to know what version of Orca you're using. My suggestion would be to use another tool. I don't know if cclib supports Molden vibrations, but that would be my suggestion. Even if not, it wouldn't be hard to write some Python to write cclib vibrations in Molden format. $\endgroup$

    $\begingroup$ Yeah, Orca 5 changed their formatting a lot, so I don’t think you’re going to get there at the moment without some coding. I’d still suggest working with the cclib team. $\endgroup$
