The EPR spectra of (A) PaN64V, (B) PaN50G/V65ins, (C) PaN64Q, (E) NeV65Δ, (F) NeN64Δ and (G) NeG50N/V65Δ recorded under increasing microwave power at T = 10.0 ± 0.5 K. The temperature dependence is shown for EPR spectra of (D) PaN64V and (H) NeN64Δ. The EPR spectra were acquired in the perpendicular mode by using the following experimental conditions: 9.662(6) GHz, in (D) and (H) the microwave powers were kept constant at 0.32 mW, modulation amplitude 0.75 mT, modulation frequency 100 KHz, 55 dB gain, sweep time 83-168 sec, time constant 82.92 msec; 4 scans were accumulated and averaged.
