Do you know what grinds my gears? People who keep saying "standard hybrid functional B3LYP". #chemchat

End of semester at the university. Final exams. The most awkward time of the year. Each student with a sad story, each exam with a flimsy excuse, each grade with a request for one more chance (and this is already the one-more-chance exam). #chemchat

I REALLY wanted to use CFOUR (Coupled-Cluster techniques for Computational Chemistry) to answer a reviewer but... Anyone can recommend a good (and free) software for CC3 calculations? #compchem #compchemsky #chemsky

My small benchmark. Thought you might find it interesting.

Shut up Billy!

A four-panel comic strip illustrating the ironic contrast between the monumental scientific effort required to create satellite internet and the way it is sometimes utilized.

Panel 1: A scientist works diligently at a desk late at night. She is looking at papers, a calculator, and a computer monitor displaying a graph. A caption box at the top reads: "THE EFFORT OF MANY SCIENTISTS".

Panel 2: A large rocket launches from a coastal launchpad on Earth, heading up toward space. A caption box reads: "ONE OF THE GREATEST TECHNOLOGICAL CHALLENGES".

Panel 3: A satellite is shown orbiting a clearly spherical Earth against the black backdrop of space. A caption box reads: "ALL OF THIS TO DELIVER INTERNET...".

Panel 4: An angry-looking man is recording himself with his smartphone. A caption box reads: "TO BILLY". Billy has a speech bubble that reads: "THE EARTH IS FLAT!!!!".

CAS(20,25) with ICECI surprisingly fast.

New paper with my colleagues at #UFRRJ and #UFRGS. In this work #ORCA nailed to show in extreme detail the formation process of a zinc complex AND the charge transfer. Yes, we have AIMD, we have DLPNO-CCSD(T) and a little bit of TD-DFT. #CompChem #ChemSky doi.org/10.1016/j.dy...
