Since things are really heating up here, let me share a personal favorite: The "Best-Practice DFT" article by Markus, Andreas, Stefan @grimmelab.bsky.social, and myself. We cast 50+ years of collective experience into "a travelers guide to modern #compchem". Enjoy the ride: doi.org/10.1002/ange...
Best‐Practice DFT Protocols for Basic Molecular Computational Chemistry**
Many chemical investigations are supported by routine calculations of molecular structures, reaction energies, barrier heights, and spectroscopic properties. Most of these quantum-chemical calculatio...

Voting is over and the slot late next Saturday (26th Juli, 2030hrs) won.

Here is the Link to the meeting: us06web.zoom.us/j/8182541363...

Password is the r2SCAN-3c basis set without the leading "def2-" (or just send me a PM ;)

Looking forward to seeing you there!

May I interest you in a deep dive into the Hohenberg-Kohn theorems and the Kohn-Sham approach? 🤓

👉 Follow the link and pick your favorite timeslot for the 3rd DFT&A lecture: www.reddit.com/r/comp_chem/...

Links to the recordings of lectures 1 (History) & 2 (Hartree-Fock) are also available there.

We are recruiting a PhD student in machine learning for photocatalysis! In this project, we will collaborate with the group of Frank Glorius @gloriusgroup.bsky.social to develop predictive tools for energy-transfer-catalyzed photocycloadditions.

Reposts appreciated!

Hey #compchem people from @grimmelab.bsky.social and elsewhere!
Over at Reddit, we have this lovely r/comp_chem Subreddit (www.reddit.com/r/comp_chem/...), where I am gauging the interest in a virtual lecture on DFT&A. Maybe this is sth for you? Pay us a visit and leave a comment!

You got a rank, you are in the top 2%. Congrats!
dermewes.bsky.social
Congratulations @grimmelab.bsky.social for an impressive 6th place across all disciplines: topresearcherslist.com

With #compchem (DFT-D) taking first place in chemistry, and Georg Kresse (VASP/PAW-PPs/DFT) taking the 2nd place (overall, 1st in physics), I'd say:

DFT is winning science :)

There's an open position with Prof. Frank Neese, together with Prof. Stefan Grime to work on the next gen. of xTB in ORCA.

Two of the most brilliant people out there in #compchem within a great group environment. It's a one-of-a-kind opportunity here!

I have seen some data, g-xTB will be a blast.

Many US students don’t know how to seek opportunities outside the US. With some help from our colleagues in EU and Canada, we could put together a consolidated website of PhD opportunities and scholarships outside the US, organized by field. There might still be time for this year in some places.

I’m having similar conversations and sharing international opportunities a lot. I’m sure for a lot of US based trainees that feels overwhelming. I moved to Europe for my postdoc.Happy to chat with any trainees about my experience if it would be helpful.

Heartbreaking chats this week with students thinking of giving up on their dreams of getting a PhD. They worry about getting in PhD programs and careers post PhD. My suggestions: don’t be hasty, think broadly incl EU & Canada, & careers beyond traditional academia. What’re you telling your students?

This is a fantastic opportunity to work together with some of the finest and most inspiring scientists I know on the best #compchem software out there. #chemsky
grimmelab.bsky.social
A unique opportunity to collaborate with our group, the Grimme lab, and Prof. Frank Neese’s department at MPI-KOFO!
Join us in integrating our latest semiempirical method, g-xTB, into ORCA – unlocking access to even more molecular properties. 📈

Our vDZP basis set utilized in the ⍵B97X-3c composite DFT method is now also available via www.basissetexchange.org (API-based: github.com/MolSSI-BSE/b...). 🎉
Many thanks to @Susi Lehtola & coworkers for jointly providing it there!

PTB (xtb-docs.readthedocs.io/en/latest/pt...) is finally available on all platforms in xtb>=6.7.0 (github.com/grimme-lab/xtb), including conda-forge – give it a try for electron densities at DFT-level with tight-binding speed and very accurate vibrational spectroscopy intensities! ⚡️ #compchem

Thanks! Yes, UKS triplets are available in almost every DFT program.
For the singlets, you will need the maximum overlap method, which is available in Q-Chem 6 (which we use because of eq. and noneq. solvation) and @faccts-orca.bsky.social ORCA6. For convenience, sample inputs are in the SI ;)

On a diverse set with exp. refs. (black), ΔUKS (red/blue) beats SCS-CC2 for ΔE(ST) at a small fraction of the cost. Further, because it's so cheap, we can optimize (in solution!) and obtain accurate emission energies! Fresh from the press today in @acs.org JPCL: doi.org/10.1021/acs.... #compchem

Wave function methods like CC2/ADC(2) are accurate (also some DHDFs), but too slow to cover large search spaces in high throughout screenings.
This is where the state-specific ΔDFT/UKS developed in cooperation with @grimmelab.bsky.social really shines
(same for classic DA-TADF and INVEST emitters):

... achieves a small enough gap with the favorable properties of the mass-produced tDABNA.
A key challenge in the (re)search for the "eierlegende Wollmilch-DABNA" is the challenging electronic structure with short-range charge-transfer (SRCT) states, which cannot be modeled efficiently with TDDFT.

Multiresonance TADF emitters are almost perfect for #OLED: brilliant deep blue emission, stable, and volatile. If only their singlet-triplet gap ΔE(ST) was a little smaller, they could harvest triplets without the need for an Ir or Pt complex. However, none of the known permutations... #compchem🧶
