I want to reproduce the results using ORCA and checking my results whether they are matching with those reported in the publications. Can I reproduce the results using ORCA against the reported calculations using Gaussian.
May I suggest that you search the papers citing ORCA? Therein, you will find details regarding the version of ORCA software used, the nature of the run, etc.
I am attaching a link to the page citing ORCA 5.0, and you can try to find papers citing the other versions.
