Single NV centers in diamond coupled by hyperfine interaction to neighboring13C nuclear spins are now widely used in the emerging quantum technologies aselements of quantum memory adjusted to NV center electron spin qubit. Fornuclear spins with low flip-flop rate, single shot readout was demonstratedunder ambient conditions. Here we report on the systematic search of suchstable NV-13C systems using density functional theory (DFT) to simulatehyperfine and spatial characteristics of all possible NV-13C complexes in theH-terminated cluster C510 [NV]-H252 hosting the NV center. Along with theexpected stable NV- axial 13C systems wherein the 13C nuclear spin is locatedon the NV axis, we found for the first time new families of positions for the13C nuclear spin exhibiting negligible hyperfine-induced flipping rates due tonear-symmetric local spin density distribution. Spatially, these positions arelocated in the diamond bilayer passing through the vacancy of the NV center andbeing perpendicular to the NV axis. Analysis of available publications showedthat, apparently, some of the predicted non-axial near-stable systems NV-13Chave already been observed experimentally. A special experiment done on one ofthese systems confirmed the prediction made
