Quantum chemical calculations for predicting the partitioning of drug molecules in the environment Regional and temporal trends in legal and illicit drug use can be tracked through monitoring of municipal wastewater, ambient air, indoor air, and house dust. To assess the analytical result for the s...

Curious how quantum chemistry can help predict how current legal and illicit drugs distribute between air, water, and organic matter, and how climate can influence this? ๐Ÿ’Š๐ŸŒก๏ธ

GDCh wrote a section about our work! Solvent and system specific radii for CPCM with consistent analytic gradients.

Check out the GDCh article (doi.org/10.1002/nadc...) or our work (doi.org/10.1002/jcc....)!

Computing hydration free energies of small molecules with first principles accuracy Free energies play a central role in characterising the behaviour of chemical systems and are among the most important quantities that can be calculated by molecular dynamics simulations. The free ene...

Big update to @jhmchem.bsky.social's preprint on "Computing solvation free energies of small molecules with first principles accuracy" now available on arXiv: arxiv.org/abs/2405.181... #compchem ๐Ÿงต

For anyone who missed it:
Particularly interested in @lukaswittmann.bsky.social on DRACO and the new DeltaSCF capabilities.

Thank you, I am happy to hear!
Let me know about your findings! I am always on the lookout for new difficult cases.

Are you curious about what's new in ORCA?
Catch my talk on the newest solvation featuresโ€”including DRACOโ€”at the ORCA 6.1 Release Event.

The ORCA 6.1 release event is coming!
here is the schedule - we will walk you through the features and you can discuss with the developers in real time.
Looking forward to it!

Weโ€™ve derived and implemented analytical SCF energy gradients for the conductor-like polarizable continuum model with non-static radii.

Another fruitful collaboration with @faccts.de!

Who knows what kind of models could be developed with non-static radii...
