Proton polarization versus time during one cycle of DNP. (a) P1(t) in R1, with the blue line indicating the sequence DNP positive followed by DNP negative and the red line indicating the sequence 5 s relaxation followed by DNP negative. (b) Red lines indicate P2(t), green lines P3(t) and blue lines P4(t); in the upper part of the diagram the sequence is DNP positive then DNP negative, while that in the lower part is relaxation followed by DNP negative.
