Understanding Nature’s Proton Highway Researchers from the Department of Molecular Physics at the Fritz Haber Institute gained new molecular insights into the high proton conductivity of phosphoric acid.

Why is phosphoric acid so good at moving positive charges? With IR #spectroscopy, a team around researchers from our Molecular Physics Department shed light on the molecular structures behind Nature's proton highway.

Interesting work on the true 3D structure of a “flat” molecule. The research team's conclusion: the molecule is not truly flat, it is chiral also in its ground state. 😯

Researchers from our Molecular Physics Department collaborated in the experimental study. Read more 👇

Watching Atoms Roam Before They Decay Watching Atoms Roam Before They Decay. New insights into a molecular decay process.

💥 Atoms and molecules can decay upon irradiation with light. But what actually happens directly before the atoms fall apart? And when exactly does the decay happen? That's what a research team from #FHI investigated: They took a movie of a fundamental decay process!
