Abstract: Theory of nuclear magnetic resonance NMR in graphene is presented. Thecanonical form of the electron-nucleus hyperfine interaction is stronglymodified by the linear electronic dispersion. The NMR shift and spin-latticerelaxation time are calculated as function of temperature, chemical potential,and magnetic field and three distinct regimes are identified: Fermi-,Dirac-gas, and extreme quantum limit behaviors. A critical spectrometerassessment shows that NMR is within reach for fully 13C enriched graphene ofreasonable size.
