We investigate nuclear spin hyperpolarization from optically polarized nitrogen vacancy centers in isotopically enriched diamonds with C13 concentrations up to 100%. C13 enrichment leads to a nitrogen vacancy electron spin resonance with a complex hyperfine structure and dynamic nuclear polarization enhancement profile. We show that strongly coupled C13 spins in the first shell surrounding a nitrogen vacancy center generate resolved hyperfine splittings, but do not act as an intermediary in the transfer of hyperpolarization of bulk nuclear spins. High levels of C13 enrichment are desirable to increase the efficiency of hyperpolarization for magnetic resonance signal enhancement, imaging contrast agents, and as a platform for quantum sensing and many-body physics.
