Pure-shift 14N MAS NMR spectra via 2-field 2D autocorrelation

The possibility to obtain isotropic 14N NMR spectra in the solid state by means of hypothetical 2-field autocorrelation magic-angle spinning 2D experiments is outlined and proven by means of numerical simulations. The resolution of the resulting pure-shift angled projections is considered for three combinations of fields. Differences with half-integer quadrupolar spins, more specifically for the static case, are briefly discussed.
