An approach for conveniently implementing low-power CN ( n ) (ν) and RN ( n ) (ν) symmetry-based band-selective mixing sequences for generating homo- and heteronuclear chemical shift correlation NMR spectra of low γ nuclei in biological solids is demonstrated. Efficient magnetisation transfer characteristics are achieved by selecting appropriate symmetries requiring the application of basic RF elements of relatively long duration and numerically tailoring the RF field modulation profile of the basic element. The efficacy of the approach is experimentally shown by the acquisition of (15)N-(13)C dipolar and (13)C-(13)C scalar and dipolar coupling mediated chemical shift correlation spectra at representative MAS frequencies.
