How to use frequencies from old ARC jobs

[amarkpayne]

Describe what you are trying to achieve I am currently trying to calculate some species thermochemistry using DLPNO in ARC. I have previously calculated the geometry/frequency for the species at a different level of theory though. Is there a way I can notify ARC of this information so that it can use it during the Arkane calculation?

There are two scenarios where I can see this happening, so this may change the approach.

1. When the geometry and frequency have been calculated by a prior ARC job
2. When the geometry and frequency have been calculated outside of ARC

Currently no, I agree it's a very desired feature. Let's talk about the best approach to implement it, it might be related to the Scheduler overhaul we'd like to make.

You could write a scripts that creates "fake" restart files with the information you want ARC to consider...
