Table 1.

The main dDNP parameters and results obtained for TriPA_DNP-sample, d₉-TriPA_DNP-sample and Trityl_DNP-sample at 6.7 T and 1.1 K are summarized. From the 1^st to 7^th column we report in order: sample name, radical concentration, ESR spectrum full-width at half-maximum measured at DNP conditions, solid-state buildup time constant T_b, solid-state back calculated ¹³C polarization, liquid-state ¹³C polarization and liquid-state relaxation time T_1n.
