Fig. 3. EPR spectra of Y(NHAr*)2 (2) in Et2O at 60 K (top) and 295 K (bottom). The black traces are the experimental spectra collected using the following conditions: microwave frequency, 9.3972 GHz (top), 9.3270 GHz (bottom); microwave power, 5 mW (top), 0.125 mW (bottom); field modulation amplitude, 0.1 mT (top), 0.4 mT (bottom). The red traces are spectra simulations offset for visualization purposes. Simulations were done with EasySpin15 using the spin Hamiltonian parameters given in the text.
