The longitudinal detected (LOD) ESR spectrum (grey curve) and the 13C DNP microwaves sweep without modulation (blue curve) and with modulation (red curve) are reported for TriPA_DNP-sample (panel A) and d9-TriPA_DNP-sample (panel B). All measurements were performed at 6.7 T and 1.1 K. Samples were UV-irradiated in liquid nitrogen for 300 s.
