The electronic spin associated with the nitrogen-vacancy (NV) centre in diamond interacts with an environment formed by isotopic impurities and paramagnetic defects; the strength of these interactions depends on the location of each impurity relative to the NV centre. From the electron spin resonance spectra of individual NV centres we infer the possible values and signs of hyperfine splittings from nearby 13C nuclear spins at different lattice sites. Moreover, single-defect-centre nuclear magnetic resonance allows the examination of some of the inhomogeneities associated with the mesoscopic environment of NV–13C systems. These measurements provide a check on ab initio calculations of electron spin density and have relevance for potential applications in nuclear spin quantum registers.

- Nitrogen-vacancy centers in diamond: nanoscale sensors for physics and biology. (2014, background): “The electron density is mostly located in a plane vertical to the main NV axis, with the highest density on the three carbon atoms and the vacant site (see Figure 3) (41, 42).”
- Measurement and Control of Single Nitrogen-Vacancy Center Spins above 600 K (2012, background): “While it has been shown that NV center spins can be optically polarized up to at least 500 K [11, 12], little is known about what processes limit the spin’s optical addressability and coherence at higher temperatures.”
