Summary

Scripts to calculate activation barriers to dissociative chemisorption from the gas phase, for 16 adsorbate-surface combinations, and compare to PBE (dispersionless) datapoints from published SBH17 dataset. This simply requires 2 single-point calculations, as E(barrier) = E(transition state) - E(gas phase) , and the results can be put on a scatter plot.

looks really good! @gkleryoung would you be able to send us the input data for the calculation so we can upload it?

Thanks for this!

Can you have a go at applying the pre-commit (see https://ddmms.github.io/ml-peg/developer_guide/get_started.html#automatic-coding-style-check (you can also run this outside of making new commits e.g. pre-commit run --all-files), just to make sure all of our tests pass

Can you add a default spin (multiplicity) and charge? See similar changes here: https://github.com/ddmms/ml-peg/pull/384/changes

I very recently discovered Orb's omol model always requires both to be set, annoyingly
