Time domain DNP at 1.2 T.

ABSTRACT: We present the results of an experimental pulsed DNP study at 1.2 T (33.5 GHz/51 MHz electron and ¹H Larmor frequencies, respectively). The results include a comparison of constant-amplitude NOVEL (CA-NOVEL), ramped-amplitude NOVEL (RA-NOVEL) and the frequency-swept integrated solid effect (FS-ISE) experiments all of which were performed at the NOVEL matching condition, ω_1S=ω_0I, where ω_1S is the electron Rabi frequency andω_0I the proton Larmor frequency. To the best of our knowledge, this is the first pulsed DNP study carried out at field higher than X-band (0.35 T) using the NOVEL condition. A combination of high microwave power (∼150 W) and a microwave cavity with a high Q (∼500) allowed us to satisfy the NOVEL matching condition. We
