Highly\u2010resolved spectra of 3\u2010carbamoyl\u20102,2,5,5\u2010tetramethylpyrrolidin\u20101\u2010yloxy, diphenylnitroxide, galvinoxyl, and perylene cation radical with excellent signal\u2010to\u2010noise are shown, demonstrating the capabilities of the rapid\u2010scan technique to characterize very small, well\u2010resolved hyperfine couplings. To acquire high resolution spectra the signal bandwidth must be less than the resonator bandwidth. Signal bandwidth is inversely proportional to linewidth and proportional to scan rate. Resonator bandwidth is inversely proportional to resonator Q. Proper selection of scan rate and resonator Q is needed to achieve resolution of closely\u2010spaced narrow EPR lines.<\/jats:p>","DOI":"10.1002\/cphc.202000701","type":"journal-article","created":{"date-parts":[[2020,9,24]],"date-time":"2020-09-24T11:15:26Z","timestamp":1600946126000},"page":"2564-2570","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Rapid\u2010Scan Electron Paramagnetic Resonance of Highly Resolved Hyperfine Lines in Organic Radicals."],"prefix":"10.1002","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8677-6405","authenticated-orcid":false,"given":"Joseph E.","family":"McPeak","sequence":"first","affiliation":[{"name":"Department of Chemistry and Biochemistry University of Denver  Denver Colorado 80210 USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter","family":"H\u00f6fer","sequence":"additional","affiliation":[{"name":"Bruker Biospin GMBH  Silberstreifen 4 Rheinstetten Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sylwia","family":"Kacprzak","sequence":"additional","affiliation":[{"name":"Bruker Biospin GMBH  Silberstreifen 4 Rheinstetten Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Patrick","family":"Carl","sequence":"additional","affiliation":[{"name":"Bruker Biospin GMBH  Silberstreifen 4 Rheinstetten Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ralph","family":"Weber","sequence":"additional","affiliation":[{"name":"Bruker BioSpin Corporation Billerica MA 01821 USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2731-7986","authenticated-orcid":false,"given":"Sandra S.","family":"Eaton","sequence":"additional","affiliation":[{"name":"Department of Chemistry and Biochemistry University of Denver  Denver Colorado 80210 USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7429-8469","authenticated-orcid":false,"given":"Gareth R.","family":"Eaton","sequence":"additional","affiliation":[{"name":"Department of Chemistry and Biochemistry University of Denver  Denver Colorado 80210 USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2020,10,20]]},"reference":[{"key":"e_1_2_7_1_1","unstructured":"\u00a0"},{"key":"e_1_2_7_2_2","doi-asserted-by":"publisher","DOI":"10.1002\/9783527672431.ch2"},{"key":"e_1_2_7_3_2","first-page":"1","volume-title":"Methods in Enzymology: Electron Paramagnetic Resonance Investigations of Biological Systems by Using Spin Labels, Spin Probes, and Intrinsic Metal Ions, Part A, Vol. 563","author":"Eaton S.
