“…Molecular oxygen is vital for human life and pivotal in many chemical processes on Earth and beyond . In several research areas, including ultracold chemistry, − combustion, , plasma, , atmospheric chemistry, surface scattering, , new physics searches, , and astrochemistry, , quantum state-resolved data is necessary to reveal the physical and chemical dynamics of O 2 . The unique and ubiquitous chemistry of oxygen results from its biradical electronic structure, which also creates severe challenges for spectroscopic detection.…”
