[DFTB-Plus-User] Spin constants for 3-ob-3-1 parameter set

[Kandes, Martin]

Hi Kewei,

Thanks for the collection. I'll take a closer look at it when I get the chance and let you know if I can add anything here to help. I've actually had some trouble compiling dftb for our new Spack-based software stack here were hoping to deploy soon on Expanse. So, it may be some time until I can get around to testing it. If anything, do you have any suggestions on the compilation options for dftb? I know there can be quite a few different variants researchers use for their individual work.

Sincerly,

Subject: [DFTB-Plus-User] Spin constants for 3-ob-3-1 parameter set

Hello,

I would like to share a complete collection of spin constants for the 3-ob-3-1 parameter set. Thanks to Prof. Elstner (one of the authors of 3-ob-3-1) for kindly providing this data.
