These observations have yielded a precisely determined set of rotational constants, electron spin-rotation parameters, and proton hyperfine coupling constants. Our results enable a quantitative comparison of the structural and electronic properties of 2-furanyloxy with those of phenoxy and other closely related radicals, providing detailed physical insights into these prototypical resonance-stabilized \u03c0 systems. The accurate laboratory rest frequencies derived from our measurements enable the quantification of the gas-phase chemistry of 2-furanyloxy in both the laboratory and in space, where the oxidation of aromatic rings remains poorly understood.<\/jats:p>","DOI":"10.1021\/acs.jpca.6c05049","type":"journal-article","created":{"date-parts":[[2026,9,9]],"date-time":"2026-09-09T16:02:21Z","timestamp":1788969741000},"page":"7706-7712","source":"Crossref","is-referenced-by-count":0,"title":["The Rotational\nSpectrum of 2-Furanyloxy Radical"],"prefix":"10.1021","volume":"130","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0304-9814","authenticated-orcid":true,"given":"P.
