Abstract
A reduced dimensionality magic angle spinning solid-state NMR experimental protocol for obtaining chemical shift correlation spectra of dipolar coupled nuclei in uniformly ((13)C, (15)N) labelled biological systems is described and demonstrated. The method involves a mapping of the evolution frequencies of heteronuclear (13)C-(15)N zero- and double-quantum coherences. In comparison to a reduced dimensionality procedure involving the simultaneous incrementation of two single-quantum chemical shift evolution periods, the approach described here could be potentially advantageous for minimising the heat dissipated in the probe by high power (1)H decoupling in experiments requiring long t (1) acquisition times.
