Credit: Cheng Feihu Based on this technology, a new device called Frequency-modulated Faraday Rotation (FM-FRS) spectrometer has been developed, which can detect OH radicals with high precision. The study was published in Optics Express. Hydroxyl (OH) radicals are important active oxidants in the atmosphere and are important reaction chain initiators in the oxidation of most compounds. In order to study their reaction processes and mechanisms in detail, they must be measured directly in "real time," i.e., to study…
