Sterically hindered free radicals. Part 20. EPR and ENDOR spectroscopy of α-carbonyl radicals

“…The hyperfine coupling constants and g values of 11 a-carbonyl radicals 'CR'R2(CRO) (1) and *CR3(CN)(CRO) (2) (R = H, Me, Ph, a-Naph; R1, R2, R3 = H, CO,Et, Ph, 2,4-Me2Ph, Mes) have been determined by EPR and, partially, ENDOR spectroscopy. The g values lie between 2.0025 and 2.0051.…”
