# Purpose Currently, cclib has the ability to parse rotational constants and molecular mass from MOPAC log files (I think this functionality was added to cclib long ago by RMG...

Gaussian

### Motivation or Problem Currently, the RMG documentation on the website is based on the current version of master. This can create problems when a user who installed the "binary"...

Full model chemistry is `#uHF dlpno-ccsd(t)-f12 cc-pvtz-f12 aug-cc-pvtz/c cc-pvtz-f12-cabs TightSCF tightPNO`. In the coming days I will do data validation on this and the other model chemistries being added, so...

Thanks to @dranasinghe for the calculations!! This PR also fixes some issues with existing species in the reference species database

Status: Review Needed

I used the method of just calculating the single atoms. For hydrogen, I just took the final energy given after the SCF stage, as Orca cannot handle the couple cluster...
