We show in this manuscript that ²H,¹³C correlation spectra in uniformly ²H,¹³C isotopically enriched peptides and proteins can be recorded in MAS solid-state NMR with site specific resolution. A resolved deuterium dimension is obtained by evolving ²H double-quantum coherences. Experimental ²H line widths are obtained that are as small as 16 Hz (0.17 ppm at 600 MHz) in the double-quantum dimension. The unprecedented resolution in the deuterium dimension obtained for proteins opens new perspectives for correlation experiments and, in particular, for the characterization of dynamics of proteins in the solid-state.
