巴塞尔大学团队在单个氮分子离子中受控测得禁戒振动跃迁：成果发表于《自然-通讯》
瑞士巴塞尔大学化学系Stefan Willitsch教授领导的团队在单个被囚禁的氮分子离子中识别并相干控制了禁戒振动跃迁。研究成果发表于《自然-通讯》，论文第一作者为Aleksandr Shlykov等人。
这类跃迁因选择定则通常难以直接激发与测量。团队采用量子逻辑光谱方法，在不破坏分子的前提下反复进行激光测量，从而读取单个分子的振动状态。
大学发布称，该方法为在单分子层面精密研究分子性质提供了新路径。论文同时在arXiv公开，编号为2603.10553。

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.
