Two main factors have previously favoured the choice of the pseudo-Wigner-Ville distribution (PWVD) over the spectrogram for time-frequency analysis of monocomponent signals. First, the PWVD has better resolution, and secondly, it provides a more accurate estimate of the instantaneous frequency. How

It is generally observed that the performance of double-resonance multiple-pulse-based \(J\) cross polarization (DCP) is superior to that of pulsed-free-precession (INEPT)-based sequences for net transfer of coherence between scalar coupled spins. Here, effects of relaxation and radiofrequency field
