In this work we investigated the time behavior of the polarization of bulk 13C nuclei in
diamond above the thermal equilibrium. This nonthermal nuclear hyperpolarization is
achieved by cross relaxation between two nitrogen related paramagnetic defect species in
diamond in combination with optical pumping. The decay of the hyperpolarization at four
different magnetic fields is measured. Furthermore, we use the comparison with conventional
nuclear resonance measurements to identify the involved distances of the nuclear spin with
respect to the defects and therefore the coupling strengths. Also, a careful look at the linewidth
of the signal give valuable information to piece together the puzzle of the hyperpolarization
mechanism.
