CCL: How to generate .47 file for NBO analysis in orca-5.0.3



Dear Thomas and Shivangi,
(These questions may have been answered elsewhere) The setup and use of NBO7 with ORCA 5.0.4 is described in the ORCA manual in section 9.43. Download it from https://orcaforum.kofo.mpg.de  at the Downloads/ORCAManuals page. To get the NBODATA.47 file in the output you need to include the "archive" parameter in the $nbo keylist section of the ORCA input.inp file.

Dear  Shivangi,

I had a similar challenge in my ongoing research. However, I used ORCA 5.0.3 with JANPA for Natural Population analysis for comparable results.

Please let me know if eventually you are able to run NBO with ORCA 5.03.

Thank you.

Kind regards.

Dear CCL Members,

I hope this email finds you well. I am writing to seek assistance in generating
a .47 file for NBO (Natural Bond Orbital) analysis using ORCA 5.0.3 and
understanding how to use this file with the gennbo tool. I am encountering
difficulties in this process and would appreciate your guidance.

Thank you for your time and support.

Sincerely,
Shivangi
