University of Basel Team Controls Forbidden Vibrational Transitions in Single Nitrogen Molecular Ions, Published in Nature Communications
A team led by Professor Stefan Willitsch in the Department of Chemistry at the University of Basel has identified and coherently controlled forbidden vibrational transitions in single trapped nitrogen molecular ions. The results were published in Nature Communications, with Aleksandr Shlykov as first author.
Such transitions are normally difficult to excite and measure directly because of selection rules. The team used quantum-logic spectroscopy to make repeatable laser measurements without destroying the molecule, reading out the vibrational state of a single molecule.
The university said the approach opens a route to precise studies of molecular properties at the single-molecule level. The paper is also available on arXiv as 2603.10553.
