X-band (9.63 GHz) EPR spectra of (A) 1-OH and (B) 1-F in 3:1 CH2Cl2-MeCN. The red lines are least-squares fits with (A) g = 2.002 and (B) = (1.99, 2.01, 2.01), and five equivalent 14N nuclei with (A) A14N = 21 MHz and (B) A14N = 16 MHz. The fit in (B) includes one 19F nucleus with A = (92, 113, 253) MHz where the coordinate system is suggested by DFT calculations described below. The small shoulder near 342 mT in (B) belongs to a minor contaminant. Experimental parameters: temperature, 27 K; microwave power, (A) 2 µW, (B) 20 µW; modulation, 0.3 mT.
