Spectral editing in 13C solid-state NMR at high magnetic field using fast MAS and spin-echo dephasing

► We propose a simple method for distinguishing protonated and non-protonated aromatic carbons under fast MAS. ► The approach uses MAS-synchronized spin-echo to exploit the differences in rotational recoupling. This strategy circumvents the rotational echo problem in the traditional dipolar dephasing method. ► The approach can be used for quantification of carbon aromaticities in complex solids.
