Current methods of creation such as elec-tronic‐nuclear spin systems are inherently probabilistic with respect to mutual location of color center electronic spin and13 C nuclear spins. A new bottom‐up approach to fabricate such systems is to synthesize first chemically appropriate diamond‐like organic molecules containing desired isotopic constituents in definite positions and then use them as a seed for diamond growth to produce mac-roscopic diamonds, subsequently creating vacancy‐related color centers in them. In particular, diamonds incorporating coupled NV‐13С spin systems (quantum registers) with specific mutual ar-rangements of NV and13C can be obtained from anisotopic azaadamantane molecule. Here we pre-dict the characteristics of hyperfine interactions (hfi) for the NV‐13 C systems in diamonds grown from various isotopically substituted azaadamantane molecules differing in13C position in the seed, as well as the orientation of the NV center in the post‐obtained diamond. We used the spatial and hfi data simulated earlier for the H‐terminated cluster C510[NV]‐ H252. The data obtained can be used to identify (and correlate with the seed used) the specific NV‐13C spin system by measuring, e.g., the hfi‐induced splitting of the mS = ±1 sublevels of the NV center in optically detected magnetic resonance (ODMR) spectra being characteristic for various NV‐13 C systems.
