A method for the inclusion of the effects of z-axis pulsed field gradients in computer simulations of an arbitrary pulsed NMR experiment with spin 1 2 nuclei is described. Recognizing that the phase acquired by a coherence following the application of a z-axis pulsed field gradient bears a fixed rel

With the advent in 1990 of pulsed-field-gradient (PFG) Here we show several alternatives to obtain phase-sensitive homonuclear 2D spectra in very short times with techniques for coherence selection in high-resolution NMR experiments, the concept of routine in chemical and bio-no phase cycling. Thus
