It has been recently shown that second-order anisotropies can be removed from solid phase NMR spectra of quadrupolar nuclei via the combined use of magic-angle spinning (MAS) and bidimensional multiple-quantum (MQ) spectroscopy. The present study investigates the conditions under which the acquisiti
The condition for an echo formation is reviewed in the context of half-integer quadrupole system. The common features of the classical echo phenomena and the coherence transfer echo are highlighted. The article also explains how the measurement of a series of coherence transfer echoes achieves the h
## Abstract A simple procedure is presented for the determination of the asymmetry parameter of the electric field gradient, the quadrupole coupling constant, the secondβorder quadrupolar shift and the isotropic chemical shift of quadrupolar nuclei with halfβinteger spin directly from the experimen
