Simulated 2D ZQC NMR spectra of aspartate. (A) Spectrum acquired with 1,500 Hz spectral bandwidth in the indirect dimension, created by 0.667 ms t1 increments. The spectrum is symmetrical around F1 = 0 with all resonances appearing at the frequency difference of the scalar-coupled spins. (B) Increasing the t1 increments to 1.33 ms reduces the spectral bandwidth to 750 Hz thereby leading to aliasing of resonances. (C) Zoomed region extracted from the spectrum shown in (B). Resonances within a multiplet are split by the scalar coupling difference with passive spins. See text for details.
