Scheme 9. (A) EPR of int-I at 20 K; (B) Mass Spectrometry Results and Postulated Mechanistic Pathways.
Experimental conditions: Power = 2.0 mW, modulation (100 kHz) amplitude 7.5 G. Dotted red trace represents the Easyspin43 (esfit) simulation with parameters g = (2.103, 2.200, 2.227). Dipolar interaction D(int-I) = 299 MHz. J coupling = 100 MHz.
